OPA1637 Description
The OPA1637 is a low-noise, low total harmonic distortion (THD), fully differential, Burr-Brown™ Audio operational amplifier that easily filters and drives fully differential, audio signal chains. The OPA1637 also converts single-ended sources to differential outputs required by high-fidelity analog-todigital converters (ADCs). Designed for exceptional low noise and THD, the bipolar super-beta inputs yield a very...
