OPA1637 Audio Fully-Differential Amplifier

Texas Instruments OPA1637 Audio Fully-Differential Amplifier is a low-noise, low total harmonic distortion (THD), fully differential, Burr-Brown™ Audio operational amplifier. It easily filters and drives fully differential audio signal chains. The OPA1637 also converts single-ended sources to differential outputs required by high-fidelity analog-to-digital converters (ADCs). Designed for exceptionally low noise and THD, the bipolar super-beta inputs yield a very low noise figure at a very low quiescent current and input bias current. Texas Instruments OPA1637 is designed for audio circuits with low power consumption, excellent signal-to-noise ratio (SNR), and spurious-free dynamic range (SFDR).
