概述

Description

The AD8638ARZ is a precision operational amplifier (op-amp) from Analog Devices, known for its low noise, low distortion, and high speed. It features a rail-to-rail output, allowing it to swing close to the supply rails, which maximizes dynamic range in single-supply applications. With a high gain-bandwidth product and a low input offset voltage, the AD8638 is suitable for a variety of applications, including instrumentation, audio processing, and active filtering.
Key specifications include a typical input offset voltage of 100 µV, a gain bandwidth of 10 MHz, and a slew rate of 20 V/µs. It operates on a supply voltage range of ±2.5V to ±15V, making it versatile for both single and dual supply designs. Additionally, the AD8638's low input bias current (10 pA) and high common-mode rejection ratio (CMRR) enhance its performance in sensitive applications. Packaged in an 8-lead SOIC or MSOP, the AD8638ARZ is an excellent choice for high-performance analog circuit designs requiring precision and stability.
