THAT5173 Overview
The THAT5173 is a digital gain controller for low-noise, analog, differential, current-feedback audio preamplifiers such as the THAT 1580 and 1583. When used in conjunction with an appropriate analog gain block, the 5173 supports digitally controlled gain from 0dB to 60dB in 3dB steps, while preserving low noise and distortion. It operates from ±5V to ±17V analog supplies, supporting input signal levels as high as...
