General Description
The ICL761X–ICL764X family of monolithic CMOS op amps combine ultra-low input current with low-power operation over a wide supply voltage range. With pin­selectable quiescent currents of 10µA, 100µA, or 1000µA per amplifier, these op amps will operate from ±1V to ±8V power supplies, or from single supplies from 2V to 16V. The CMOS outputs swing to within milli­volts of the supply voltages.
The ultra-low bias current of 1pA makes this family of op amps ideal for long time constant integrators, picoammeters, low droop rate sample/hold amplifiers and other applications where input bias and offset cur­rents are critical. A low noise current of 0.01pA√Hz and an input impedance of 1012Ω ensure optimum perfor­mance with very high source impedances in such applications as pH meters and photodiode amplifiers.
Applications

Detailed Description
Quiescent Current Selection
The voltage input to the IQpin of the single and triple amplifiers selects a quiescent current (I
Q
) of 10µA, 100µA, or 1000µA. The dual and quad amplifiers have fixed quiescent current (IQ) settings. Unity-gain band­width and slew-rate increase with increasing quiescent current, as does output sink current capability. The out­put source current capability is independent of quies­cent current.
The lowest I
Q
setting that results in sufficient bandwidth and slew rate should be selected for each specific application.
The IQpin of the single and triple amplifiers controls the quiescent current as follows:
Input Offset Nulling
The input offset can be nulled by connecting a 25kΩ pot between the OFFSET terminals with the wiper con­nected to V+. At quiescent currents of 1mA and 100µA, the nulling range provided is adequate for all V
OS
selections. However, with higher values of VOS, and an IQof 10µA, nulling may not be possible.
Frequency Compensation
All of the ICL7611 and ICL7621 series except the ICL7614 are internally compensated for unity-gain operation. The ICL7614 is externally compensated by a capacitor connected between COMP and OUT pins, with 39pF being greater than unity. The compensation capacitor value may be reduced to increase the band­width and slew rate. The ICL7132 is not compensated and does not have frequency compensation pins. Use only at gains 20 at IQof 1mA; at gains > 10 at IQof 100µA; at gain > 5 at IQof 10µA.
Output Loading Considerations
Approximately 70% of the amplifier’s quiescent current flows in the output stage. The output swing can approach the supply rails for output loads of 1MΩ, 100kΩ, and 10kΩ, using the output stage in a highly linear Class A mode. Crossover distortion is avoided
and the voltage gain is maximized in this mode. The output stage, however, can also be operated in Class AB, which supplies higher output currents (see the
Typical Operating Characteristics
). The voltage gain decreases and the output transfer characteristic is non­linear during the transition from Class A to Class B operation.
The output stage, with a gain that is directly proportion­al to load impedance, approximates a transconduc­tance amplifier. Approximately the same open-loop gains are obtained at each of the IQsettings if corre­sponding loads of 10kΩ, 100kΩ, and 1MΩ are used.
The maximum output source current is higher than the maximum sink current, and is independent of IQ.
Like most amplifiers, there are output loads for which the amplifier stability is not guaranteed. In particular, avoid capacitive loads greater than 100pF; and while on the 1mA IQsetting, avoid loads less than 5kΩ. Since the output stage is a transconductance output, very large (>10µF) capacitive loads will create a dominant pole and the output will be stable, even with loads that are less than 5kΩ.
Extended Common-Mode Voltage Range
(ICL7612/ICL7616)
A common-mode voltage range that includes both V+ and V- is often desirable, especially in single-supply operation. The ICL7612/ICL7616 extended common­mode range op amps are designed specifically to meet this need. The ICL7612 input common-mode voltage range (CMVR) extends beyond both power-supply rails when operated with at least 3V total supply and an I
Q
of 10µA or 100µA. The ICL7616 CMVR includes the negative supply voltage (or ground when operated with a single supply) at an IQor 10µA or 100µA.
PC Board Layout
Careful PC board layout techniques must be used to take full advantage of the very low bias current of the ICL7611 family. The inputs should be encircled with a low-impedance trace, or guard, that is at the same potential as the inputs. In an inverting amplifier, this is normally ground; in a unity-gain buffer connect the guard to the output. A convenient way of guarding the 8-pin TO-99 version of the ICL7611 is to use a 10-pin circle, with the two extra pads on either side of the input pins to provide space for a guard ring (see Figure
8). Assembled boards should be carefully cleaned, and if a high humidity environment is expected, confor­mally coated.

Single/Dual/Triple/Quad Operational Amplifiers
22 ______________________________________________________________________________________
Single-Supply Operation
The ICL7611 family will operate from a single 2V to 16V power supply. The common-mode voltage range of the standard amplifier types when operated from a single supply is 1.0V to (V+ - 0.6V) at 10µA I
Q
. At 100µA IQ, the CMVR is 1.0V to (V+ - 0.8V), and at 1mA IQ, the CMVR is 1.3V to (V+ - 1.3V). If this CMVR range is insufficient, use the ICL7612, whose CMVR includes both ground and V+, or the ICL7616, whose CMVR includes ground.
A convenient way to generate a psuedo-ground at V+/2 is to use one op amp of a quad to buffer a V+/2 voltage from a high-impedance resistive divider.
Low-Voltage Operation
Operation at V
SUPP
= ±1.0V is only guaranteed at IQ= 10µA. Output swings to within a few millivolts of the supply rails are achievable for RL(> or =) 1MΩ. Guaranteed input CMVR is ±0.6V minimum and typical­ly +0.9V to -0.7V at V
SUPP
= ±1.0V. For applications where greater common-mode range is desirable, see the description of ICL7612 and ICL7616 above.
Applications Information
Note that in no case is IQ shown. The value of IQ must be chosen by the designer with regard to frequency response and power dissipation.

Figure 3. Level Detector—By using the ICL7612 in these appli­cations, the circuits will follow rail-to-rail inputs.
Figure 4. Photocurrent Integrator—Low-leakage currents allow integration times up to several hours.
Figure 5. Precise Triangle/Square Wave Generator—The fre­quency and duty cycle are virtually independent of power sup­ply.

Figure 10. Long-Time Constant Integrator—With RIN= 1011
Ω
, the time constant of this integrator is 100,000s. Since the input voltage is converted to a current by R
IN
, the input voltage can
far exceed the power-supply range.
Figure 11. Pico Ammeter—The response time of this curcuit is R
FB
x CFB, where CFBis the stray capacitance between the
output and the inverting terminal of the amplifier.
Figure 12. 60Hz Twin “T“ Notch Filter—The low 1pA bias cur­rent of the ICL7611 allows use of small 540pF and 270pF capacitors, even with a notch frequency of 60Hz. The 60Hz rejection is approximately 40dB.
