AK2922H

Overview

The AK2922H is a dual-channel zero-drift operational amplifier designed for precision analog signal conditioning. It features an ultra-low input offset voltage and current, with a maximum input bias current of 50 pA. The device offers a gain-bandwidth product of 4 MHz and a slew rate of 5V/µs. Operating temperatures range from -40°C to 125°C. It is housed in an 8-MSOP package.

Feature Summary

• Dual-channel architecture for multi-signal processing
• Zero-drift technology ensures high precision stability
• Ultra-low input bias current minimizes loading effects

Applications

• Precision sensor signal conditioning
• Medical instrumentation front-ends
• High-resolution data acquisition systems

Procurement Notes

Verify the specific package variant (8-MSOP) against design requirements. Confirm that the obsolete status does not impact long-term supply chain stability for production runs. Ensure compatibility with existing PCB footprints and soldering profiles during integration.

Selection Notes

Select this component when low drift and high input impedance are critical. Compare bandwidth and slew rate against application speed requirements. Consider the dual-channel configuration to reduce board space compared to single-channel alternatives.

Part Context
