MCP6V66/6U/7/9
80 µA, 1 MHz Zero-Drift Op Amps
Features
General Description
• High DC Precision:
The Microchip Technology Inc. MCP6V66/6U/7/9
family of operational amplifiers provides input offset
voltage correction for very low offset and offset drift.
These devices have a gain bandwidth product of
1 MHz (typical). They are unity-gain stable, have
virtually no 1/f noise and have good Power Supply
Rejection Ratio (PSRR) and Common Mode Rejection
Ratio (CMRR). These products operate with a single
supply voltage as low as 1.8V, while drawing
80 µA/amplifier (typical) of quiescent current.
- VOS Drift: ±150 nV/°C (maximum)
- VOS: ±25 µV (maximum)
- AOL: 110 dB (minimum, VDD = 5.5V)
- PSRR: 110 dB (minimum, VDD = 5.5V)
- CMRR: 111 dB (minimum, VDD = 5.5V)
- Eni: 0.54 µVP-P (typical), f = 0.1 Hz to 10 Hz
- Eni: 0.17 µVP-P (typical), f = 0.01 Hz to 1 Hz
• Enhanced EMI Protection:
The Microchip Technology Inc. MCP6V66/6U/7/9 op
amps are offered in single (MCP6V66 and
MCP6V66U), dual (MCP6V67) and quad (MCP6V69)
packages. They were designed using an advanced
CMOS process.
- Electromagnetic Interference Rejection Ratio
(EMIRR) at 1.8 GHz: 101 dB
• Low Power and Supply Voltages:
- IQ: 80 µA/amplifier (typical)
- Wide Supply Voltage Range: 1.8V to 5.5V

3.1
Analog Outputs
3.4
Exposed Thermal Pad (EP)
The analog output pins (VOUT) are low-impedance
voltage sources.
There is an internal connection between the exposed
thermal pad (EP) and the VSS pin; they must be
connected to the same potential on the printed circuit
board (PCB).
3.2
Analog Inputs
This pad can be connected to a PCB ground plane to
provide a larger heat sink. This improves the package
thermal resistance (θJA).
The noninverting and inverting inputs (VIN+, VIN-, …)
are high-impedance CMOS inputs with low bias
currents.
3.3
Power Supply Pins
The positive power supply (VDD) is 1.8V to 5.5V higher
than the negative power supply (VSS). For normal
operation, the other pins are between VSS and VDD
.
Typically, these parts are used in a single (positive)
supply configuration. In this case, VSS is connected to
ground and VDD is connected to the supply. VDD will
need bypass capacitors.

The Low-Pass Filter reduces high-frequency content,
including harmonics of the chopping clock.

APPLICATIONS
The MCP6V66/6U/7/9 family of zero-drift op amps is
manufactured using Microchip’s state-of-the-art CMOS
process. It is designed for applications with
requirements for small packages and low power. Its low
supply voltage and low quiescent current make the
MCP6V66/6U/7/9 devices ideal for battery-powered
applications.
The Output Buffer drives external loads at the VOUT pin
(VREF is an internal reference voltage).
The Oscillator runs at fOSC1 = 200 kHz. Its output is
divided by two to produce the chopping clock rate of
fCHOP = 100 kHz.
The internal Power-on Reset (POR) starts the part in a
known good state, protecting against power supply
brown-outs.
4.1
Overview of Zero-Drift Operation
The Digital Control block controls switching and POR
events.
Figure 4-1 shows
a
simplified diagram of the
MCP6V66/6U/7/9 zero-drift op amps. This diagram will
be used to explain how slow voltage errors are reduced
in this architecture (much better VOS, VOS/TA (TC1),
CMRR, PSRR, AOL and 1/f noise).
4.1.2
CHOPPING ACTION
Figure 4-2 shows the amplifier connections for the first
phase of the chopping clock, and Figure 4-3 shows the
connections for the second phase. Its slow voltage
errors alternate in polarity, making the average error
small.

The Main Amplifier is designed for high gain and
bandwidth, with a differential topology. Its main input
pair (+ and - pins at the top left) is used for the higher
frequency portion of the input signal. Its auxiliary input
pair (+ and - pins at the bottom left) is used for the
low-frequency portion of the input signal, and corrects
the op amp’s input offset voltage. Both inputs are
added together internally.

The Auxiliary Amplifier, Chopper Input Switches and
Chopper Output Switches provide a high DC gain to the
input signal. DC errors are modulated to higher
frequencies, while white noise is modulated to low
frequency.

These op amps will show intermodulation distortion
(IMD) products when an AC signal is present.
The signal and clock can be decomposed into sine
wave tones (Fourier series components). These tones
interact with the zero-drift circuitry’s nonlinear response
to produce IMD tones at sum and difference
frequencies. Each of the square wave clock’s
harmonics has a series of IMD tones centered on it.

voltage is high enough to allow normal operation but
not low enough to protect against slow overvoltage
(beyond VDD) events. Very fast ESD events (that meet
the specification) are limited so that damage does not
occur.
The input stage of the MCP6V66/6U/7/9 op amps uses
two differential CMOS input stages in parallel. One
operates at low Common Mode Input Voltage (VCM
,
which is approximately equal to VIN+ and VIN- in normal
operation) and the other at high VCM. With this
topology, the input operates with VCM up to VDD + 0.3V
and down to VSS – 0.2V, at +25°C (see Figure 2-16).
The input offset voltage (VOS) is measured at
VCM = VSS – 0.2V and VDD + 0.3V to ensure proper
operation.
In some applications, it may be necessary to prevent
excessive voltages from reaching the op amp inputs;
Figure 4-5 shows one approach to protecting these
inputs. D1 and D2 may be small signal silicon diodes,
Schottky diodes for lower clamping voltages or
diode-connected FETs for low leakage.

Phase Reversal
The input devices are designed to not exhibit phase
inversion when the input pins exceed the supply
voltages. Figure 2-41 shows an input voltage
exceeding both supplies with no phase inversion.

In order to prevent damage and/or improper operation

Table 1-1 gives both the linear and quadratic

voltage. The input offset voltage, at any temperature in
the specified range, can be calculated as follows:
Figure 4-6 shows one approach to protecting these

current in or out of the input pins (and into D1 and D2).

When these parts power up, the input offset (VOS
)
starts at its uncorrected value. Circuits with high DC
gain can cause the output to reach one of the two rails.
In this case, the time to a valid output is delayed by an
output overdrive time (like tODR) in addition to the
start-up time (like tSTR).
FIGURE 4-6:
Against High Currents.
Protecting the Analog Inputs
It can be simple to avoid this extra start-up time.
Reducing the gain is one method. Adding a capacitor
across the feedback resistor (RF) is another method.
It is also possible to connect the diodes to the left of the
R1 and R2 resistors. In this case, the currents through
the D1 and D2 diodes need to be limited by some other
mechanism. The resistors then serve as in-rush current
limiters; the DC current into the input pins (VIN+ and
VIN-) should be very small.
A significant amount of current can flow out of the inputs
(through the ESD diodes) when the Common Mode
Voltage (VCM) is below ground (VSS) (see Figure 2-15).
4.2.2
RAIL-TO-RAIL OUTPUT
The Output Voltage Range of the MCP6V66/6U/7/9
zero-drift op amps is VDD – 5.9 mV (typical) and
VSS + 4.7 mV (typical) when RL = 20 kΩ is connected to
VDD/2 and VDD = 5.5V. Refer to Figures 2-17 and 2-18
for more information.
This op amp is designed to drive light loads; use
another amplifier to buffer the output from heavy loads.

GN is the circuit’s noise gain. For noninverting gains,
GN and the Signal Gain are equal. For inverting gains,
GN is 1+|Signal Gain| (e.g., -1 V/V gives GN = +2 V/V).
4.3.3
SOURCE RESISTANCES
The input bias currents have two significant
components: switching glitches that dominate at room
temperature and below and input ESD diode leakage
currents that dominate at +85°C and above.

VDD = 5.5V
RL = 20 kȍ
Make the resistances seen by the inputs small and

input bias currents.

100
The inputs should see a resistance on the order of 10Ω
to 1 kΩ at high frequencies (i.e., above 1 MHz). This
helps minimize the impact of switching glitches, which
are very fast, on overall performance. In some cases it
may be necessary to add resistors in series with the
inputs to achieve this improvement in performance.

SOURCE CAPACITANCE
After selecting RISO for your circuit, double check the
resulting frequency response peaking and step
response overshoot. Modify the RISO value until the
response is reasonable. Bench evaluation is helpful.
The capacitances seen by the two inputs should be
small. Large input capacitances and source
resistances, together with high gain, can lead to
positive feedback and instability.
4.3.6
STABILIZING OUTPUT LOADS
4.3.5
CAPACITIVE LOADS
This family of zero-drift op amps has an output
impedance (Figures 2-28 and 2-29) that has a double
zero when the gain is low. This can cause a large phase
shift in feedback networks that have low-impedance
near the part’s bandwidth. This large phase shift can
cause stability problems.
Driving large capacitive loads can cause stability
problems for voltage feedback op amps. As the load
capacitance increases, the feedback loop’s phase
margin decreases and the closed-loop bandwidth is
reduced. This produces gain peaking in the frequency
response, with overshoot and ringing in the step
response. These zero-drift op amps have a different
output impedance than most op amps, due to their
unique topology.
Figure 4-9 shows that the load on the output is
(RL + RISO)||(RF + RG), where RISO is before the load
(like Figure 4-7). This load needs to be large enough to
maintain stability; it should be at least 10 kΩ.
When driving a capacitive load with these op amps, a
series resistor at the output (RISO in Figure 4-7)
improves the feedback loop’s phase margin (stability)
by making the output load resistive at higher
frequencies. The bandwidth will be generally lower
than the bandwidth with no capacitive load.

REDUCING UNDESIRED NOISE
AND SIGNALS
Figure 4-10 shows an op amp circuit that represents
noninverting amplifiers (VM is a DC voltage and VP is
the input) or inverting amplifiers (VP is a DC voltage
and VM is the input). The CN and CG capacitances
represent the total capacitance at the input pins; they
include the op amp’s Common Mode Input
Capacitance (CCM), board parasitic capacitance and
any capacitor placed in parallel. The CFP capacitance
represents the parasitic capacitance coupling the
output and noninverting input pins.
Reduce undesired noise and signals with:
• Low bandwidth signal filters:
- Minimize random analog noise
- Reduce interfering signals
• Good PCB layout techniques:
- Minimize crosstalk
- Minimize parasitic capacitances and
inductances that interact with fast switching
edges
• Good power supply design:
- Isolation from other parts

With this family of operational amplifiers, the power

of the pin for good high-frequency performance.

These parts also need a bulk capacitor (i.e., 1 µF or
larger) within 100 mm to provide large, slow currents.
This bulk capacitor can be shared with other low-noise
analog parts.
FIGURE 4-10:
Capacitance.
Amplifier with Parasitic
CG acts in parallel with RG (except for a gain of +1 V/V),
which causes an increase in gain at high frequencies.
CG also reduces the phase margin of the feedback
loop, which becomes less stable. This effect can be
reduced by either reducing CG or RF||RG.
In some cases, high-frequency power supply noise
(e.g., switched mode power supplies) may cause
undue intermodulation distortion with a DC offset shift;
this noise needs to be filtered. Adding a small resistor
into the supply connection can be helpful.
CN and RN form a low-pass filter that affects the signal

PCB DESIGN FOR DC PRECISION
at VP. This filter has a single real pole at 1/(2πRNCN).
The largest value of RF that should be used depends
on noise gain (see GN in Section 4.3.5 “Capacitive
Loads”), CG and the open-loop gain’s phase shift. An
approximate limit for RF is:
In order to achieve DC precision on the order of ±1 µV,
many physical errors need to be minimized. The design
of the Printed Circuit Board (PCB), the wiring and the
thermal environment have a strong impact on the
precision achieved. A poor PCB design can easily be
more than 100 times worse than the MCP6V66/6U/7/9
op amps’ minimum and maximum specifications.

PCB Layout
Any time two dissimilar metals are joined together, a
temperature-dependent voltage appears across the
junction (the Seebeck or thermojunction effect). This
effect is used in thermocouples to measure
temperature. The following are examples of
thermojunctions on a PCB:
Some applications may modify these values to reduce
either output loading or gain peaking (step-response
overshoot).
At high gains, RN needs to be small in order to prevent
positive feedback and oscillations. Large CN values
can also help.

Typical Applications
4.4.1
WHEATSTONE BRIDGE
Microchip’s AN1258 (“Op Amp Precision Design: PCB
Layout Techniques”) contains in-depth information on
PCB layout techniques that minimize thermojunction
effects. It also discusses other effects, such as
crosstalk, impedances, mechanical stresses and
humidity.
Many sensors are configured as Wheatstone bridges.
Strain gauges and pressure sensors are two common
examples. These signals can be small and the
Common mode noise large. Amplifier designs with high
differential gain are desirable.
Figure 4-11 shows how to interface to a Wheatstone
bridge with a minimum of components. Because the
circuit is not symmetric, the ADC input is single-ended
and there is a minimum of filtering; the CMRR is good
enough for moderate Common mode noise.
4.3.10.2
Crosstalk
DC crosstalk causes offsets that appear as a larger
input offset voltage. Common causes include:
• Common mode noise (remote sensors)
• Ground loops (current return paths)
• Power supply coupling

Note the following details of the code protection feature on Microchip devices:
•
Microchip products meet the specification contained in their particular Microchip Data Sheet.
•
Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the
intended manner and under normal conditions.
•
There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our
knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data
Sheets. Most likely, the person doing so is engaged in theft of intellectual property.
•
•
Microchip is willing to work with the customer who is concerned about the integrity of their code.
Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not
mean that we are guaranteeing the product as “unbreakable.”
Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of our
products. Attempts to break Microchip’s code protection feature may be a violation of the Digital Millennium Copyright Act. If such acts
allow unauthorized access to your software or other copyrighted work, you may have a right to sue for relief under that Act.
Information contained in this publication regarding device
applications and the like is provided only for your convenience
and may be superseded by updates. It is your responsibility to
ensure that your application meets with your specifications.
