MAX9265GCM/V+ - Maxim Integrated

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 pin-

selectable 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 milli-

volts 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 cur-

rents are critical. A low noise current of 0.01pA√Hz and

an input impedance of 1012Ωensure optimum perfor-

mance with very high source impedances in such

applications as pH meters and photodiode amplifiers.

Applications

Battery-Powered Instruments

Low-Leakage Amplifiers

Detailed Description

Quiescent Current Selection

The voltage input to the IQpin of the single and triple

amplifiers selects a quiescent current (IQ) of 10µA,

100µA, or 1000µA. The dual and quad amplifiers have

fixed quiescent current (IQ) settings. Unity-gain band-

width and slew-rate increase with increasing quiescent

current, as does output sink current capability. The out-

put source current capability is independent of quies-

cent current.

The lowest IQsetting 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 con-

nected to V+. At quiescent currents of 1mA and 100µA,

the nulling range provided is adequate for all VOS

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 band-

width 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 non-

linear during the transition from Class A to Class B

operation.

The output stage, with a gain that is directly proportion-

al to load impedance, approximates a transconduc-

tance amplifier. Approximately the same open-loop

gains are obtained at each of the IQsettings if corre-

sponding loads of 10kΩ, 100kΩ, and 1MΩare 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 common-

mode 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 IQ

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, confor-

mally 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 IQ. 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 VSUPP = ±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 typical-

ly +0.9V to -0.7V at VSUPP = ±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.
