ICL7616ACPA

Overview

The ICL7616ACPA is a single-channel operational amplifier manufactured by Analog Devices Inc./Maxim Integrated. It features a voltage-feedback architecture with low bias current characteristics, specifically designed for precision applications requiring minimal input loading. The device operates within a supply voltage range of 2 V to 16 V and supports through-hole mounting in an 8-pin SOIC package. Key electrical parameters include a maximum input offset voltage of 3 mV, a nominal common-mode rejection ratio of 80 dB, and a frequency-compensated design ensuring stability in standard configurations.

Feature Summary

• Low bias current operation suitable for high-impedance signal sources
• Internal frequency compensation for stable performance
• Single-channel general-purpose amplification capability

Applications

• Precision instrumentation circuits
• High-impedance sensor interfaces
• Signal conditioning stages

Procurement Notes

Verify the specific package variant, as datasheets indicate SOIC availability while other listings reference PDIP. Confirm RoHS compliance status directly with the manufacturer or authorized distributors, as historical records show mixed compliance data for this part number. Ensure the selected component matches the required pinout and thermal specifications for the target PCB layout before finalizing procurement orders.

Selection Notes

Select this component when low input bias current is critical for maintaining signal integrity in high-impedance circuits. The internal frequency compensation simplifies design by reducing the need for external phase compensation components. Verify that the 80 dB CMRR meets the system's noise rejection requirements and that the 3 mV max offset voltage aligns with the application's accuracy constraints.

Part Context

This component belongs to the ICL761x series of operational amplifiers from Maxim Integrated, now part of Analog Devices. The series is known for combining low power consumption with precision performance metrics. The ICL7616ACPA represents a specific iteration optimized for general-purpose analog signal processing tasks where moderate bandwidth and low input current are prioritized over high-speed slew rates.

Replacement Considerations

Direct replacement options include the ICL7616ACSA, which shares similar electrical characteristics but utilizes an SOIC package instead of the DIP format. Verify pin compatibility and package dimensions before substitution to ensure mechanical fit within the existing assembly.
