MCP6L91/1R/2/4

10 MHz, 850 µA Op Amps

Features

Description

• Available in SOT-23-5 package

The Microchip Technology Inc. MCP6L91/1R/2/4 family

of operational amplifiers (op amps) provides wide

bandwidth for the current. The input bias currents and

voltage ranges make it easier to fit into many

applications.

• Gain Bandwidth Product: 10 MHz (typical)

• Rail-to-Rail Input/Output

• Supply Voltage: 2.4V to 6.0V

• Supply Current: I_Q= 0.85 mA/amplifier (typical)

• Extended Temperature Range: -40°C to +125°C

• Available in Single, Dual and Quad Packages

This family has a 10 MHz Gain Bandwidth Product

(GBWP) and a low 850 µA per amplifier quiescent

current. These op amps operate on supply voltages

between 2.4V and 6.0V, with rail-to-rail input and output

swing. They are available in the extended temperature

range.

Analog Outputs

3.3

Power Supply Pins

The analog output pins (V_OUT) are low-impedance

voltage sources.

The positive power supply (V_DD) is 2.4V to 6.0V higher

than the negative power supply (V_SS). For normal

operation, the other pins are between V_SSand V_DD

.

3.2

Analog Inputs

Typically, these parts are used in a single (positive)

supply configuration. In this case, V_SSis connected to

ground and V_DDis connected to the supply. V_DDwill

need bypass capacitors.

The non-inverting and inverting inputs (V_IN+, V_IN–, …)

are high-impedance CMOS inputs with low bias

currents.

DS22141A-page 9

MCP6L91/1R/2/4

NOTES:

DS22141A-page 10

MCP6L91/1R/2/4

A significant amount of current can flow out of the

inputs (through the ESD diodes) when the common

mode voltage (V_CM) is below ground (V_SS); see

Figure 2-7. Applications that are high impedance may

need to limit the usable voltage range.

4.0

APPLICATION INFORMATION

The MCP6L91/1R/2/4 family of op amps is manufac-

tured using Microchip’s state of the art CMOS process.

It is designed for low cost, low power and general pur-

pose applications. The low supply voltage, low

quiescent current and wide bandwidth makes the

MCP6L91/1R/2/4 ideal for battery-powered applica-

tions.

4.1.3

NORMAL OPERATION

The input stage of the MCP6L91/1R/2/4 op amps use

two differential CMOS input stages in parallel. One

operates at low common mode input voltage (V_CM),

while the other operates at high V_CM. WIth this

topology, and at room temperature, the device

operates with V_CMup to 0.3V above V_DDand 0.3V

below V_SS(typical at 25°C).

4.1

Rail-to-Rail Inputs

4.1.1

PHASE REVERSAL

The MCP6L91/1R/2/4 op amps are designed to

prevent phase inversion when the input pins exceed

the supply voltages. Figure 2-10 shows an input

voltage exceeding both supplies without any phase

reversal.

The transition between the two input stages occurs

when V_CM= V_DD– 1.1V. For the best distortion and

gain linearity, with non-inverting gains, avoid this region

of operation.

4.1.2

INPUT VOLTAGE AND CURRENT

LIMITS

4.2

Rail-to-Rail Output

The output voltage range of the MCP6L91/1R/2/4 op

amps is V_DD– 20 mV (minimum) and V_SS+ 20 mV

(maximum) when R_L= 10 kΩ is connected to V_DD/2

and V_DD= 5.0V. Refer to Figure 2-13 for more informa-

tion.

In order to prevent damage and/or improper operation

of these amplifiers, the circuit they are in must limit the

currents (and voltages) at the input pins (see

Section 1.1 “Absolute Maximum Ratings †”).

Figure 4-1 shows the recommended approach to

protecting these inputs. The internal ESD diodes

prevent the input pins (V_IN+ and V_IN–) from going too

far below ground, and the resistors R₁and R₂limit the

possible current drawn out of the input pins. Diodes D₁

and D₂prevent the input pins (V_IN+ and V_IN–) from

going too far above V_DD, and dump any currents onto

4.3

Capacitive Loads

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.

V_DD

.

V_DD

When driving large capacitive loads with these op

amps (e.g., > 100 pF when G = +1), a small series

resistor at the output (R_ISOin Figure 4-2) improves the

feedback loop’s stability by making the output load

resistive at higher frequencies; the bandwidth will

usually be decreased.

Bench measurements are helpful in choosing R_ISO

.

Adjust R_ISOso that a small signal step response (see

Figure 2-14) has reasonable overshoot (e.g., 4%).

Supply Bypass

Guard Ring

V_IN– V_IN+

With this family of operational amplifiers, the power

supply pin (V_DDfor single supply) should have a local

bypass capacitor (i.e., 0.01 µF to 0.1 µF) within 2 mm

for good high frequency performance. It also needs 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 nearby analog parts.

Example guard ring layout.

pedance Gain Amplifiers (convert current to

voltage, such as photo detectors).

Unused Op Amps

An unused op amp in a quad package (e.g., MCP6L94)

should be configured as shown in Figure 4-3. These

circuits prevent the output from toggling and causing

crosstalk. Circuit A sets the op amp at its minimum

noise gain. The resistor divider produces any desired

reference voltage within the output voltage range of the

op amp; the op amp buffers that reference voltage.

Circuit B uses the minimum number of components

and operates as a comparator, but it may draw more

current.

a) Connect the guard ring to the non-inverting

input pin (V_IN+); this biases the guard ring

to the same reference voltage as the op

amp’s input (e.g., V_DD/2 or ground).

b) Connect the inverting pin (V_IN–) to the input

with a wire that does not touch the PCB sur-

face.

2. Non-inverting Gain and Unity-Gain Buffer.

a) Connect the guard ring to the inverting input

pin (V_IN–); this biases the guard ring to the

common mode input voltage.

ACTIVE LOW-PASS FILTER

The MCP6L91/1R/2/4 op amp’s low input noise and

good output current drive make it possible to design

low noise filters. Reducing the resistors’ values also

reduces the noise and increases the frequency at

which parasitic capacitances affect the response.

These trade-offs need to be considered when selecting

circuit elements.

PCB Surface Leakage

Figure 4-5 shows a third-order Chebyshev filter with a

1 kHz bandwidth, 0.2 dB ripple and a gain of +1 V/V.

The component values were selected using Micro-

chip’s FilterLab^®software. Resistor R₃was reduced in

value by increasing C₃in FilterLab.

In applications where low input bias current is critical,

PCB (printed circuit board) surface leakage effects

need to be considered. Surface leakage is caused by

humidity, dust or other contamination on the board.

Under low humidity conditions, a typical resistance

between nearby traces is 10¹²Ω. A 5V difference would

cause 5 pA of current to flow; this is greater than this

family’s bias current at 25°C (1 pA, typical).

The easiest way to reduce surface leakage is to use a

guard ring around sensitive pins (or traces). The guard

ring is biased at the same voltage as the sensitive pin.

Figure 4-4 is an example of this type of layout.

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.

hold harmless Microchip from any and all damages, claims,
