Add To BomAD8221AR General Description
The AD8221AR is a precision, low-power, dual-channel operational amplifier designed for a wide range of applications including instrumentation, medical equipment, telecommunications, and precision audio equipment. It offers high precision with a gain bandwidth product of 24MHz, a fast settling time of 1.7μs, and low offset voltage of 150μV. The dual-channel configuration allows for flexibility in system design and provides excellent matching between channels.The AD8221AR operates on a wide supply voltage range of ±1.35V to ±18V, making it suitable for battery-powered applications or single-supply voltage systems. It features a low input bias current of 350pA and a low input offset current of 20pA, ensuring accuracy in low-level signal amplification. The amplifier also has a high common-mode rejection ratio (CMRR) of 94dB, minimizing interference from noise and ensuring a clean signal output.Other key features of the AD8221AR include a unity-gain stable design, thermal shutdown protection, and compatibility with standard op-amp circuits. The IC is housed in an 8-lead SOIC package, making it easy to integrate into existing circuit designs.
