ADIAD8221ARZ
Overview
The AD8221ARZ is a high-performance, gain-programmable instrumentation amplifier that delivers industry-leading Common-Mode Rejection Ratio (CMRR) over frequency. It is designed to extract small signals in the presence of large common-mode noise, maintaining high precision even at 10 kHz. This circuit operates on a single gain-setting resistor, making it highly versatile for precision signal conditioning.
Why Choose This Part
The AD8221ARZ offers a low input offset voltage of 60 uV and a low input bias current of 500 pA, minimizing errors in high-impedance applications. Its 825 kHz bandwidth and 2 V/us slew rate provide excellent dynamic performance compared to standard instrumentation amplifiers.
Applications
Key Specifications
Getting Started
Engineers can evaluate this part using the AD8221-EVALZ evaluation board, which provides a pre-configured layout for gain setting and signal routing. When designing the PCB, place the gain-setting resistor as close as possible to pins 1 and 8 to minimize parasitic capacitance and maintain high-frequency CMRR.
