ICL7612BESA+

Overview

The ICL7612BESA+ is a single-channel monolithic CMOS operational amplifier from the ICL761X–ICL764X family, housed in an 8-pin Slim Small Outline (SO) package. It features an extended common-mode voltage range and programmable quiescent currents of 10µA, 100µA, or 1000µA per amplifier. The device operates from ±1V to ±8V dual supplies or 2V to 16V single supplies. Key electrical characteristics include a typical input bias current of 1pA, a unity-gain bandwidth of 0.044MHz at 10µA, and an input offset voltage maximum of 5mV.

Feature Summary

• Monolithic low-power CMOS design with ultra-low input bias current
• Extended common-mode voltage range specific to the ICL7612 variant
• Pin-selectable quiescent currents for adjustable performance trade-offs
• 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 that the ordering suffix 'E' corresponds to the -40°C to +85°C operating temperature range and 'SA' indicates the 8-pin Slim SO package. Confirm RoHS compliance status as indicated by the '+' suffix. Ensure the component matches the manufacturer's official datasheet specifications before integration into production circuits.

Selection Notes

Select this component when high source impedance applications require minimal input bias current. The ICL7612 variant specifically offers an extended common-mode voltage range compared to other members of the family. Choose the appropriate quiescent current setting based on required bandwidth and slew rate versus power consumption constraints.

Part Context

This part belongs to the ICL761X–ICL764X family of single, dual, triple, and quad operational amplifiers manufactured by Analog Devices Inc./Maxim Integrated. The family combines ultra-low input current with low-power operation over a wide supply voltage range, making it suitable for precision analog signal processing tasks requiring minimal power draw.

Replacement Considerations

The ICL7612DESA+ serves as a direct replacement within the same package and temperature range. Other family members like the ICL7611 or ICL7616 may be considered if their specific common-mode voltage ranges align with application requirements.
