ADA4622-1BRZ-RL

Overview

The ADA4622-1BRZ-RL is a single-channel, precision JFET input operational amplifier manufactured by Analog Devices Inc. It operates within a supply voltage range of 5 V to 30 V and supports an extended industrial temperature range from -40°C to +125°C. Key electrical specifications include a typical gain bandwidth product of 8 MHz, a low-to-high slew rate of 23 V/µs, and a maximum input bias current of ±10 pA at 25°C. The device features rail-to-rail output capability and B-grade offset voltage limits of ±0.35 mV with a drift of ±1 µV/°C.

Feature Summary

• JFET input architecture providing extremely low input bias current for high-impedance signal sources
• Rail-to-rail output stage enabling full dynamic range utilization in single-supply applications
• Integrated electromagnetic interference (EMI) rejection filters to maintain signal integrity near switching noise
• B-grade precision specifications ensuring minimal offset voltage and thermal drift

Applications

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

Procurement Notes

Verify the specific B-grade performance parameters against the official datasheet tables for your operating temperature and supply voltage conditions. Confirm that the SOT-23-5 package dimensions align with your PCB footprint requirements. Ensure ESD precautions are observed during handling due to the sensitivity of the JFET input stage.

Selection Notes

Select this component when low input bias current and high DC precision are required in a compact surface-mount package. The B-grade variant offers tighter offset voltage and drift specifications compared to the A-grade version. Consider the 8 MHz bandwidth and 23 V/µs slew rate for moderate-speed signal processing tasks requiring rail-to-rail output swing.

Part Context

This part belongs to the ADA4622 family, which serves as the next-generation replacement for the AD820 series. While the ADA4622-1 is available in multiple packages including LFCSP, the BRZ suffix specifically denotes the 8-lead SOIC_N package configuration. The RL suffix indicates reel packaging for automated assembly processes.
