ICL7612BCSA

Overview

The ICL7612BCSA+T is a single-channel, low-power CMOS operational amplifier from the ICL761X–ICL764X family. It features ultra-low input bias current of 50 pA and operates over a wide supply voltage range of 1V to 8V or 2V to 16V. Key electrical parameters include a gain-bandwidth product of 44 kHz, a slew rate of 16 mV/us, an input offset voltage of 5 mV, and a power supply current of 15 uA. The device provides a common-mode rejection ratio of 60 dB and an input voltage noise density of 100 nV/sqrt Hz. It is housed in an SOIC-8 surface-mount package and supports operation temperatures from -40°C to +85°C.

Feature Summary

• Ultra-low input bias current suitable for high-impedance signal sources
• Low quiescent power consumption for battery-operated applications
• Wide single or dual supply voltage operation capability

Applications

• Long time constant integrators
• Picoammeters
• Low droop rate sample/hold amplifiers

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and specific suffix designations against official datasheets. Check for obsolescence notices or lifecycle changes as availability may be restricted. Ensure storage conditions meet moisture sensitivity level requirements prior to assembly.

Selection Notes

Select this component when ultra-low input bias current is critical for maintaining signal integrity in high-impedance circuits. The low power consumption makes it suitable for portable devices. Compare performance metrics such as bandwidth and noise against other members of the ICL761X family to ensure compatibility with specific circuit requirements and environmental operating ranges.

Part Context

This part belongs to the ICL761X–ICL764X series of monolithic CMOS operational amplifiers manufactured by Analog Devices / Maxim Integrated. The series combines ultra-low input current with low-power operation across a wide supply voltage range. These amplifiers are designed for applications requiring minimal input loading and extended battery life.

Replacement Considerations

Check for pin-compatible alternatives within the same ICL761X family. Verify that substitute components match the required input bias current, supply voltage range, and package type. Consult official documentation for any functional differences between variants.
