ADA4622-4ACPZ-RL

Overview

The ADA4622-4ACPZ-RL is a quad precision operational amplifier from Analog Devices Inc., featuring JFET inputs and rail-to-rail output capability. It operates within a supply voltage range of 5 V to 30 V across an extended industrial temperature range of -40°C to +125°C. The device offers an 8 MHz gain bandwidth product, a typical slew rate of 23 V/µs, and low input bias current with a maximum of ±10 pA at 25°C. Packaged in a 16-lead LFCSP (4 × 4 mm) format, it provides four independent amplifiers designed for high-speed signal processing applications.

Feature Summary

• JFET input architecture providing extremely low input bias current
• Rail-to-rail output swing capability for maximizing dynamic range
• High electromagnetic interference rejection ratio for robust signal integrity
• Industry-standard pinouts facilitating direct upgrades from legacy devices

Applications

• High output impedance sensor interfaces
• Photodiode sensor interfaces
• Transimpedance amplifiers
• ADC drivers
• Precision filters and signal conditioning

Procurement Notes

Verify the specific package type and grade against the datasheet requirements before procurement. Confirm that the ordering suffix matches the desired reel quantity and packaging specifications. Ensure compatibility with the intended operating temperature range and supply voltage conditions specified in the electrical characteristics tables.

Selection Notes

Select this component when multiple precision channels are required in a compact footprint. The quad configuration reduces board space compared to single-channel alternatives. Consider the thermal resistance characteristics of the LFCSP package for heat dissipation planning. Evaluate the trade-off between the high slew rate and power consumption based on the application's speed requirements.

Part Context

This part belongs to the ADA4622 series, which serves as the next generation of the AD820/AD822/AD824 family. It improves upon previous models by offering reduced broadband noise, lower offset voltage, and improved common-mode rejection ratio while maintaining similar supply current levels. The series is designed for single-supply operation with rail-to-rail output performance.
