Overview
The NE5534PSRG4, produced by Texas Instruments, is a high-performance operational amplifier that combines excellent DC and AC characteristics. This device is part of the NE5534 family, which includes the NE5534, NE5534A, SA5534, and SA5534A. These operational amplifiers are known for their very low noise, high output-drive capability, high unity-gain and maximum-output-swing bandwidths, low distortion, and high slew rate. They are internally compensated for a gain equal to or greater than three and offer optimization of the frequency response through an external compensation capacitor between the COMP and COMP/BAL pins.
