ICL7612BCSA+T

Overview

The ICL7612BCSA+T is a single-channel monolithic CMOS operational amplifier from the ICL761X–ICL764X family. It features an input bias current of 50 pA maximum and an input offset voltage of 5 mV maximum at +25°C. The device operates on supply voltages ranging from ±1 V to ±8 V or single supplies from 2 V to 16 V, with a quiescent current of 15 µA maximum. It utilizes an 8-pin Small Outline package and supports an operating temperature range of 0°C to +70°C.

Feature Summary

• Ultra-low input bias current for high-impedance source applications
• Pin-selectable quiescent current control via external connection
• Rail-to-rail output swing capability within millivolts of supply rails
• Monolithic low-power CMOS design architecture

Applications

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

Procurement Notes

Verify the specific suffix 'BCSA' against official documentation to confirm the B-grade offset voltage specification (5mV max) and C-grade commercial temperature range (0°C to +70°C). Ensure the '+T' designation aligns with required reel packaging specifications. Cross-reference the manufacturer's latest datasheet to validate RoHS compliance status and confirm availability through authorized distribution channels.

Selection Notes

Select this component when ultra-low input bias current is critical for maintaining signal integrity in high-impedance circuits. The ICL7612 variant specifically offers extended common-mode voltage range compared to other members of the family. Consider the programmable quiescent current feature to optimize the trade-off between bandwidth, slew rate, and power consumption based on application requirements.

Part Context

This part belongs to the ICL761X–ICL764X series of general-purpose operational amplifiers manufactured by Analog Devices / Maxim Integrated. The series combines low power operation with extremely low input currents, making it suitable for precision analog signal conditioning tasks where minimal loading of the signal source is required.

Replacement Considerations

The ICL7612ACSA+T serves as a direct pin-compatible alternative offering tighter offset voltage tolerances (2mV max) but maintains identical pinouts and electrical characteristics.
