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.

This process, in conjunction with unique chopper-

stabilization circuitry, produces an operational

amplifier whose performance matches or

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

ideal choice for low-Ievel signal-processing

applications such as strain gauges, thermo-

couples, and other transducer amplifiers.

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.

ICL7652 Advanced LinCMOSTM PRECISION OPERATIONAL AMPLIFIER CHOPPER-STABILIZED TYPICAL capacitor selection APPLICATION DATA and placement The two important factors to consider when selecting external capacitors CXA and CXB are leakage and dielectric absorption. Both factors can cause system degradation that negate the performance advantages realized by using the ICL7652. Degradation from capacitor leakage becomes more apparent with increasing temperatures.

Advanced TYPICAL avoiding ICL7652 PRECISION CHOPPER-STABILIZED OPERATIONAL AMPLIFIER LinCMOSTM APPLICATION DATA latchup The ICL7652 inputs and output are designed to withstand -1 OO-mA surge currents without sustaining latchup. However, because CMOS devices are susceptible to latchup due to their inherent parasitic thyristors, techniques to reduce the chance of latchup should be used whenever possible. Internal protection diodes should not be forward biased in normal operation.

ICL7652 Advanced LinCMOSTM PRECISION OPERATIONAL AMPLIFIER CHOPPER-STABILIZED TYPICAL APPLICA TION DA T A The low-frequency noise of a chopper amplifier depends on the magnitude of the component noise prior to chopping and the capability of the circuit to reduce this noise while chopping. The use of the Advanced linCMOSTM process, with its low-noise analog MOS transistors and patent-pending input stage design, significantly reduces the input noise voltage.
