Overview
The NE5534ADR is a high-performance, low-noise operational amplifier produced by Texas Instruments. It is part of the NE5534 and SA5534 family, known for their excellent DC and AC characteristics. These operational amplifiers are designed to offer very low noise, high output-drive capability, high unity-gain and maximum-output-swing bandwidths, low distortion, and a high slew rate. They are internally compensated for a gain equal to or greater than three and can be optimized for various applications using an external compensation capacitor.
