Overview
The ADA4622-2ACPZ-RL is a dual-channel precision operational amplifier from Analog Devices, featuring JFET inputs and rail-to-rail output. It operates on supply voltages ranging from 5 V to 30 V (±2.5 V to ±15 V) with an operating temperature range of -40°C to +125°C. Key electrical specifications include a typical gain bandwidth product of 8 MHz, a slew rate of 23 V/µs, and a maximum input bias current of 10 pA at 25°C. The device offers low offset voltage drift and high common-mode rejection ratio.
Feature Summary
- Next-generation upgrade to the AD822 series with improved DC precision and reduced noise
- Rail-to-rail output capability with input voltage range including the negative supply rail
- High electromagnetic interference rejection ratio for robust signal integrity in noisy environments
- Industry-standard pinouts and package options for easy design integration
Applications
- High output impedance sensor interfaces
- Photodiode sensor interfaces
- Transimpedance amplifiers
- ADC drivers
- Precision filters and signal conditioning
Procurement Notes
Verify the specific grade (A or B) and thermal resistance requirements against your application needs. Confirm that the LFCSP package exposed pad connection aligns with your PCB layout guidelines. Ensure ESD precautions are observed during handling due to the sensitivity of the JFET input stage.
Selection Notes
Select this component when upgrading from legacy AD822 designs requiring lower offset voltage drift and higher CMRR. Consider the ACPZ-RL suffix for volume manufacturing via reel packaging. Evaluate the trade-off between the 8 MHz bandwidth and the ultra-low input bias current for high-impedance source applications.
Part Context
This part belongs to the ADA4622 family, which includes single (ADA4622-1), dual (ADA4622-2), and quad (ADA4622-4) variants. The dual-channel version provides two independent amplifiers in a compact footprint, designed to replace older precision op-amps while offering enhanced performance metrics such as reduced broadband noise and improved settling times.
Replacement Considerations
Direct replacements include other parts within the ADA4622 family (ADA4622-1, ADA4622-4) depending on channel count requirements. Legacy equivalents like the AD822 may be compatible but lack the improved DC precision and noise characteristics.
