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 at +25°C and operates within a supply voltage range of ±1V to ±8V, or single supplies from 2V to 16V. The device offers extended common-mode voltage range capabilities and includes offset null functionality. It is housed in an 8-pin Slim Small Outline package with a commercial operating temperature range of 0°C to +70°C.

Feature Summary

• Ultra-low input bias current for high-impedance source applications
• Extended common-mode voltage range capability
• Pin-selectable quiescent current settings for performance optimization
• Internal offset nulling terminals

Applications

• Long time constant integrators
• Picoammeters
• Low-leakage amplifiers
• Low-frequency active filters
• Sample/hold amplifiers

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging configuration. Confirm that the 'B' designation corresponds to the specified 5mV input offset voltage grade. Ensure the 'C' temperature code matches the required 0°C to +70°C operating environment. Cross-reference the manufacturer's latest datasheet revision to confirm pinout compatibility and electrical characteristics.

Selection Notes

Select this component when ultra-low input bias current is critical for maintaining signal integrity in high-impedance circuits. The extended common-mode range allows operation closer to the negative supply rail compared to standard variants. Consider the programmable quiescent current feature if bandwidth or slew rate requirements exceed the default low-power setting.

Part Context

This part belongs to the ICL761X–ICL764X series of monolithic CMOS operational amplifiers manufactured by Analog Devices / Maxim Integrated. The series combines low power consumption with extremely low input currents, making it suitable for precision analog front-end designs requiring minimal loading on sensitive signal sources.

Replacement Considerations

The ICL7612ACSA-T serves as a direct pin-for-pin second source alternative within the same family, offering a tighter 2mV input offset voltage specification while maintaining identical pinouts and general electrical characteristics.
