GENERAL DESCRIPTION
The ADA4610-1/ADA4610-2/ADA4610-4 are precision junction
field effect transistor (JFET) amplifiers that feature low input noise
voltage, current noise, offset voltage, input bias current, and rail-to-
rail output. The ADA4610-1 is a single amplifier, the ADA4610-2 is
a dual amplifier, and the ADA4610-4 is a quad amplifier.
performance filters. Low input bias currents, low offset, and low
noise result in a wide dynamic range for photodiode amplifier
circuits. Low noise and distortion, high output current, and
excellent speed make the ADA4610-1/ADA4610-2/ADA4610-4
great choices for audio applications.
The combination of low offset, noise, and very low input bias
current makes these amplifiers especially suitable for high
impedance sensor amplification and precise current measurements
using shunts. With excellent dc precision, low noise, and fast
settling time, the ADA4610-1/ADA4610-2/ADA4610-4 provide
superior accuracy in medical instruments, electronic measurement,
and automated test equipment. Unlike many competitive
amplifiers, the ADA4610-1/ADA4610-2/ADA4610-4 maintain
fast settling performance with substantial capacitive loads. Unlike
many older JFET amplifiers, the ADA4610-1/ADA4610-2/
ADA4610-4 do not suffer from output phase reversal when input
voltages exceed the maximum common-mode voltage range.
The ADA4610-1/ADA4610-2/ADA4610-4 are specified over
the −40°C to +125°C extended industrial temperature range.
The ADA4610-1 is available in an 8-lead SOIC package and in a
5-lead SOT-23 package. The ADA4610-2 is available in 8-lead
SOIC, 8-lea d M S O P, a n d 8 -lead LFCSP packages. The ADA4610-4
is available in a 14-lead SOIC package and in a 16-lead LFCSP.

Data Sheet
THEORY OF OPERATION
The ADA4610-1/ADA4610-2/ADA4610-4 are manufactured
using the Analog Devices, Inc., iPolar® process, a 36 V dielectrically
isolated (DI) process with P-channel JFET technology. The
unique architecture of the ADA4610-1/ADA4610-2/ADA4610-4
makes it possible to combine high precision and high speed
characteristics into a high voltage, low power op amp. A simplified
schematic for the ADA4610-1/ADA4610-2/ADA4610-4 is
shown in Figure 57. The JFET input stage architecture offers
advantages of low input bias current, high bandwidth, high
gain, low noise, and no phase reversal when the applied input
signal exceeds the common-mode voltage range. The output
stage is rail-to-rail with high drive characteristics and low
dropout voltage for both sinking and sourcing currents.
The ADA4610-1/ADA4610-2 B grades achieve less than 0.4 mV
of offset and 4 µV/°C of offset drift; these characteristics are
usually associated with very high precision bipolar input amplifiers.
The gate current of a typical JFET doubles every 10°C, resulting
in a similar increase in input bias current over temperature. The
low power consumption characteristic of the ADA4610-1/
ADA4610-2/ADA4610-4 minimizes the die temperature, which
warrants low input bias currents even at elevated ambient tem-
peratures, making the amplifiers ideal for applications that require
low leakage specifications without active cooling. Ensure proper
printed circuit board (PCB) layout to minimize leakage currents
between PCB traces. Improper layout and board handling can
generate leakage currents exceeding the bias currents of the
operational amplifier.
The ADA4610-1/ADA4610-2/ADA4610-4 are unconditionally
stable for all gain configurations, even with capacitive loads well
in excess of 1 nF. The devices have internal protective circuitry
that allows voltages as high as 0.3 V beyond the supplies to be
applied at the input of either terminal without causing damage (for
higher input voltages, refer to the Input Overvoltage Protection
section).
The ADA4610-1/ADA4610-2/ADA4610-4 are fully specified with
supply voltages from 5 V to 15 V over the extended industrial
temperature range of −40°C to +125°C. The ADA4610-1 is
available in an 8-lead SOIC. The ADA4610-2 is available in an
8-lead MSOP, an 8-lead SOIC, and an 8-lead LFCSP. The
ADA4610-4 is available in a 14-lead SOIC and a 16-lead LFCSP.
All these packages are surface-mount type.

ADA4610-1/ADA4610-2/ADA4610-4
APPLICATIONS INFORMATION
The ADA4610-1/ADA4610-2/ADA4610-4, shown in Figure 58,
are ideal for building a peak detector because U2A requires dc
precision and high output current during fast peaks, and U2B
requires low input bias current (IB) to minimize capacitance
discharge between peaks. A low leakage and low dielectric
absorption capacitor, such as polystyrene or polypropylene, is
required for C3. Reversing the diode directions causes the
circuit to detect negative peaks.
INPUT OVERVOLTAGE PROTECTION
The ADA4610-1/ADA4610-2/ADA4610-4 have internal protective
circuitry that allows voltages as high as 0.3 V beyond the supplies
to be applied at the input of either terminal without causing
damage. For higher input voltages, a series resistor is necessary
to limit the input current. Determine the resistor value by

where:
VIN is the input voltage.
VS is the voltage of either V+ or V−.
RS is the series resistor.
Common applications for I to V conversion include photodiode
circuits where the amplifier converts a current emitted by a diode
placed at the negative input terminal into an output voltage.
With a very low bias current of <1.5 nA up to 125°C, higher
resistor values can be used in series with the inputs. A 5 kΩ
resistor protects the inputs from voltages as high as 25 V
beyond the supplies and adds less than 10 µV to the offset.
The low input bias current, wide bandwidth, and low noise of
the ADA4610-1/ADA4610-2/ADA4610-4 make them excellent
choices for various photodiode applications, including fax
machines, fiber optic controls, motion sensors, and barcode
readers.
PEAK DETECTOR
The function of a peak detector is to capture the peak value of a
signal and produce an output equal to it. By taking advantage of
the dc precision and super low input bias current of the JFET input
amplifiers, such as the ADA4610-1/ADA4610-2/ADA4610-4, a
highly accurate peak detector can be built, as shown in Figure 58.
The circuit shown in Figure 59 uses a silicon diode with zero
bias voltage. This setup is a photovoltaic mode, which uses
many large photodiodes. This configuration limits the overall
noise and is suitable for instrumentation applications.

In this application, Diode D3 and Diode D4 act as unidirectional
current switches that open up when the output is kept constant (in
hold mode). To detect a positive peak, U2A drives C3 through D3
and D4 until C3 is charged to a voltage equal to the input peak
value. Feedback from the output of the U2B + peak through R6
limits the output voltage of U2A. After detecting the peak, the
output of U2A swings low but is clamped by D2. Diode D3
reverses bias and the common node of D3, D4, and R7 is held to a
voltage equal to + peak by R7. The voltage across D4 is 0 V;
therefore, its leakage is small. The bias current of U2B is also small.
With almost no leakage, C3 has a long hold time.
Figure 59. Equivalent Preamplifier Photodiode Circuit
A larger signal bandwidth can be attained at the expense of
additional output noise. The total input capacitance (CT) consists of
the sum of the diode capacitance (typically 30 pF to 40 pF) and
the amplifier input capacitance (<10 pF), which includes external
parasitic capacitance. CT creates a zero in the frequency response
that can lead to an unstable system. To ensure stability and
optimize the bandwidth of the signal, place a capacitor in the
feedback loop of the circuit shown in Figure 59. The capacitor
creates a pole and yields a bandwidth with a corner frequency of
1/(2π(RFCF))
where:
RF is the feedback resistor.
CF is the feedback capacitor.

Determine the RF value by the following ratio:
COMPARATOR OPERATION
V/ID
Although op amps are quite different from comparators,
occasionally an unused section of a dual or a quad op amp can
be used as a comparator; however, this is not recommended for
rail-to-rail output op amps. For rail-to-rail output op amps, the
output stage is generally a ratioed current mirror with bipolar or
MOSFET transistors. With the device operating in open-loop
mode, the second stage increases the current drive to the ratioed
mirror to close the loop. However, the second stage cannot close
the loop, which results in an increase in supply current. With
the ADA4610-1/ADA4610-2/ADA4610-4 op amps configured
as comparators, the supply current can be significantly higher
(see Figure 60 for the supply current vs. the supply voltage for the
ADA4610-4). Configuring an unused section as a voltage follower
with the noninverting input connected to a voltage within the
input voltage range is recommended. The ADA4610-1/ADA4610-2/
ADA4610-4 have a unique output stage design that reduces the
excess supply current but does not entirely eliminate this effect
when the op amp is operating in open-loop mode.
where:
V is the desired output voltage of the op amp.
ID is the diode current.
For example, if ID is 100 µA and a 10 V output voltage is needed,
RF must be 100 kΩ. The resistance of the photodiode (RD) is a
junction resistance (see Figure 59).
A typical value for RD is 1000 MΩ. Because RD >> RF, the circuit
behavior is not impacted by the effect of the junction resistance.
The maximum signal bandwidth (fMAX) is

2πRFCT

LONG-TERM DRIFT
TEMPERATURE HYSTERESIS
The stability of a precision signal path over its lifetime or
between calibration procedures is dependent on the long-term
stability of the analog components in the path, such as op amps,
references, and data converters. To help system designers
predict the long-term drift of circuits that use the ADA4610-1/
ADA4610-2/ADA4610-4, Analog Devices measured the offset
voltage of multiple units for 10,000 hours (more than 13 months)
using a high precision measurement system, including an
ultrastable oil bath. To replicate real-world system performance,
the devices under test (DUTs) were soldered onto an FR4 PCB
using a standard reflow profile (as defined in the JEDEC J-STD-
020D standard), as opposed to testing them in sockets. This
manner of testing is important because expansion and
In addition to stability over time as described in the Long-Term
Drift section, it is useful to know the temperature hysteresis,
that is, the stability vs. cycling of temperature. Hysteresis is an
important parameter because it tells the system designer how
closely the signal returns to its starting amplitude after the
ambient temperature changes and subsequent return to room
temperature. Figure 62 shows the change in input offset voltage
as the temperature cycles three times from room temperature to
125°C to −40°C and back to room temperature. The dotted line
is an initial preconditioning cycle to eliminate the original
temperature-induced offset shift from exposure to production
solder reflow temperatures. In the three full cycles, the offset
hysteresis is typically only 8 µV, or 1% of its 800 µV maximum
offset voltage over the full operating temperature range. The
histogram in Figure 63 shows that the hysteresis is larger when
the device is cycled through only a half cycle, from room
temperature to 125°C and back to room temperature.
contraction of the PCB can apply stress to the integrated circuit
(IC) package and contribute to shifts in the offset voltage.
The ADA4610-1/ADA4610-2/ADA4610-4 have extremely low
long-term drift, as shown in Figure 61. The red, blue, and green
traces show sample units. Note that the ADA4610-1/
ADA4610-2/ADA4610-4 (B-grade) have a mean drift over
10,000 hours of approximately 5 µV, or less than 2% of their
maximum specified offset voltage of 400 µV at room
temperature.
