descri ption
D package is available taped and reeled. Add "R" suffix to device
type (i.e., ICL7652DR).
The ICL7652 is a precision chopper-stabilized
operational amplifier manufactured using Texas
Instruments Advanced LinCMOSTM process.
DISTRIBUTION OF ICl7652
INPUT OFFSET VOl TAG E
This process, in conjunction with unique chopper-
stabilization circuitry, produces an operational
amplifier whose performance
matches or
32
exceeds that of similar devices available today.
Chopper stabilization techniques make possible
extremely high dc precision by continuously
nulling input offset voltage even with variations in
temperature, time, common-mode voltage, and
supply voltage. Additionally, low-frequency noise
voltage is significantly reduced. This precision,
coupled with the extremely high input impedance
of the CMOS input stage, makes the ICL7652 an

The ICL7652 input common-mode range includes
VIO -Input Offset Voltage -~V
the negative rail, thereby providing superior
performance in either single-supply or split-
supply applications, even at supply voltages as low as :t1.9 V. The ICL7652 also features fast overload
recovery time. Two external capacitors are required to operate the device; however, the on-chip chopper
control circuitry is transparent to the user .
The device inputs and output are designed to withstand -100-mA surge currents without sustaining latchup.
Additionally, the ICL7652 incorporates internal ESD protection circuits that prevent functional failures at
voltages up to 2000 Vas tested under MIL-STD-883C, Method 3015; however, care should be exercised in
handling these devices, as exposure to ESD may result in degradation of the device parametric performance.
The ICL7652 is characterized for operation from O°C to 70°C.
