ICL7612DESA+T

Overview

The ICL7612DESA+T is a single-channel, low-power CMOS operational amplifier from the ICL761X–ICL764X family. It features an extended common-mode voltage range and operates on supply voltages ranging from ±1V to ±8V or 2V to 16V single supply. The device offers a typical input bias current of 50pA, a unity-gain bandwidth of 44kHz, and a slew rate of 16mV/µs at the lowest quiescent setting. Packaged in an 8-pin SOIC (Slim Small Outline) format, it supports an industrial temperature range of -40°C to +85°C.

Feature Summary

• Monolithic CMOS design with ultra-low input bias current for high-impedance source applications
• Extended common-mode voltage range specific to the ICL7612 variant
• Rail-to-rail output swing capability approaching supply voltages
• Industry-standard pinouts compatible with legacy designs

Applications

• Long-time constant integrators
• Picoammeters
• Low droop rate sample/hold amplifiers
• pH meters and photodiode amplifiers

Procurement Notes

Verify the component's active status directly with Analog Devices or Maxim Integrated distributors, as availability may be restricted. Confirm that the ordering suffix corresponds to the Slim SO package and the specified temperature grade. Ensure compliance with RoHS directives and check for any recent product change notices affecting manufacturing locations or materials.

Selection Notes

Select this part when extended common-mode voltage range is required alongside low power consumption. Compare against other variants in the ICL761X series based on offset voltage requirements and available quiescent current settings. Consider the trade-off between bandwidth and power dissipation if higher performance is needed by adjusting internal current settings.

Part Context

This component belongs to the ICL761X–ICL764X family of monolithic CMOS operational amplifiers. The family combines ultra-low input current with low-power operation over a wide supply voltage range. Variants within the family differ by channel count, offset voltage grades, and package types, sharing core architectural features like programmable quiescent currents.

Replacement Considerations

Check for pin-compatible second sources listed in the official datasheet. Verify that substitute parts maintain the extended common-mode voltage range characteristic of the ICL7612 model.
