ICL7612BESA

Overview

The ICL7612BESA is a single-channel CMOS operational amplifier from the ICL761X family, manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 2V to 16V or ±1V to ±8V. Key electrical parameters include a gain-bandwidth product of 44 kHz, a slew rate of 16 mV/µs, and an input bias current of 50 pA. The device features a maximum input offset voltage of 5 mV and a quiescent current of 15 µA. It provides a common-mode rejection ratio of 60 dB and an input voltage noise density of 100 nV/√Hz. The component 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 processing
• Rail-to-rail output capability with millivolt proximity to supply rails
• Pin-selectable quiescent current options for power optimization

Applications

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

Procurement Notes

Verify availability status as distribution channels may indicate limited stock or discontinuation. Confirm RoHS compliance details through official datasheets. Ensure the specific suffix matches required packaging formats such as cut tape or reel. Cross-reference manufacturer part numbers to avoid counterfeit components during sourcing.

Selection Notes

Select this component for applications requiring ultra-low input bias currents and low power consumption. The CMOS architecture allows operation over a wide supply voltage range. Consider the trade-off between bandwidth and power dissipation when designing circuits. Verify that the SOIC-8 package fits the target PCB layout constraints.

Part Context

This device belongs to the ICL761X–ICL764X family of monolithic CMOS operational amplifiers. The family combines ultra-low input current characteristics with low-power operation. These amplifiers are designed for precision analog applications where minimal loading on high-impedance sources is critical.

Replacement Considerations

Check for direct pin-compatible substitutes within the same CMOS op-amp family. Verify that alternative components meet the specific 50 pA input bias current requirement. Ensure replacement parts support the same 2V to 16V supply voltage range.
