ICL7616ACSA

Overview

The ICL7616ACSA is a single operational amplifier from the ICL761X–ICL764X family, manufactured by Maxim Integrated. It features ultra-low input bias current of 1pA typical and low-power CMOS design. The device operates on wide supply voltages ranging from ±1V to ±8V or single supplies from 2V to 16V. It includes offset null capability and programmable quiescent currents for the family, though this specific single variant has fixed settings. The output swings within millivolts of the supply rails.

Feature Summary

• Ultra-low input bias current of 1pA typical
• Wide supply voltage range operation
• Offset null capability
• Rail-to-rail output swing

Applications

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

Procurement Notes

Verify the manufacturer designation as Maxim Integrated in official documentation. Confirm the package type is 8-pin Small Outline (SO) and the temperature range is C Series (0°C to +70°C). Ensure compatibility with existing circuit designs regarding pinout and electrical specifications before procurement.

Selection Notes

Select this component when extremely low input bias current is critical for signal integrity. It is suitable for high-impedance source applications such as pH meters and photodiode amplifiers. Consider the operating temperature range and supply voltage requirements to ensure it meets the system's environmental and power constraints.

Part Context

This part belongs to the ICL761X–ICL764X family of monolithic CMOS operational amplifiers. The family combines ultra-low input current with low-power operation. Variants include single, dual, triple, and quad configurations with different compensation and quiescent current options.

Replacement Considerations

The datasheet indicates pin-for-pin second sources are available for this family. Verify exact electrical parameter matches and package dimensions when substituting with other manufacturers' offerings.
