Single/Dual/Triple/Quad
Operational Amplifiers
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
the CMVR is 1.0V to (V+ - 0.8V), and at 1mA I
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.

CMRR. The offset of all three amplifiers is nulled by the offset
adjustment of A2.

supply rails are achievable for R
Guaranteed input CMVR is ±0.6V minimum and typical-
ly +0.9V to -0.7V at V
where greater common-mode range is desirable, see
the description of ICL7612 and ICL7616 above.
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.
