AD8624ACPZ-R7

Overview

The AD8624ACPZ-R7 is a quad precision operational amplifier from Analog Devices, featuring rail-to-rail output swing and low power consumption. It operates within a supply voltage range of ±2.5 V to ±15 V (5 V to 30 V single supply). Key electrical specifications include a maximum input offset voltage of 125 μV, an input bias current of 200 pA maximum, and a gain-bandwidth product of 560 kHz. The device maintains performance across an extended industrial temperature range of −40°C to +125°C.

Feature Summary

• Features input bias current cancellation circuitry for very low bias current over the full operating temperature range.
• Provides rail-to-rail output swing capability while maintaining unity gain stability.
• Designed with high precision characteristics including low offset voltage drift and low voltage noise density.

Applications

• Portable precision instrumentation
• Laser diode control loops
• Strain gage amplifiers
• Medical instrumentation
• Thermocouple amplifiers

Procurement Notes

Verify the specific package option and suffix against the manufacturer's ordering guide to ensure compatibility with the required reel or cut tape format. Confirm RoHS compliance status as indicated by the 'Z' suffix in the part number. Cross-reference the datasheet revision history to ensure all electrical characteristics match the intended design requirements before finalizing procurement.

Selection Notes

Select this component when designing circuits requiring multiple precision channels with minimal power dissipation. The quad configuration reduces board space compared to individual dual packages. Ensure the application benefits from the rail-to-rail output capability and verify that the 560 kHz bandwidth meets the signal processing speed requirements for the specific system architecture.

Part Context

This component belongs to the AD8622/AD8624 family of low-power, precision op amps. The AD8624 specifically provides four independent amplifiers in a single package, whereas the AD8622 offers two. Both share identical electrical characteristics and are designed for applications demanding high accuracy and low quiescent current in portable or battery-operated systems.

Replacement Considerations

Direct functional replacements within the same series include the AD8624ARUZ (14-lead TSSOP) and AD8624ACPZ-RL. Verify pinout compatibility and thermal resistance differences when substituting between the LFCSP and TSSOP packages to ensure proper heat dissipation and mechanical fit.
