Overview
The SA5532DR is a high-performance dual low-noise operational amplifier produced by Texas Instruments. It combines excellent DC and AC characteristics, making it suitable for a wide range of applications. The device features very low noise, high output-drive capability, high unity-gain and maximum-output-swing bandwidths, low distortion, and a high slew rate. Additionally, it includes input-protection diodes and output short-circuit protection, and is internally compensated for unity-gain operation.
