ICL7652에 대한 설명
The ICL7652 is a precision chopper-stabilized operational amplifier manufactured using Texas Instruments Advanced LinCMOS™ 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-level signal-processing applications such as strain gauges, thermocouples, and other transducer amplifiers.
The ICL7652 input common-mode range includes the negative rail, thereby providing superior performance in either single-supply or split-supply applications, even at supply voltages as low as ±1.9 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 V as 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.
