Overview
The NE5534DRG4 is a high-performance operational amplifier produced by Texas Instruments. It is part of the NE5534 and SA5534 series, known for their excellent DC and AC characteristics. These operational amplifiers are designed to offer very low noise, high output-drive capability, and high unity-gain and maximum-output-swing bandwidths. They are internally compensated for a gain equal to or greater than three and feature input-protection diodes, output short-circuit protection, and offset-voltage nulling capability.
