Full Description

The THAT5173 is a digital gain controller for low-noise, analog, differential, current-feedback audio preamplifiers such as the THAT 1570 and 1583. When used in conjunction with an appropriate analog gain block, the 5173 supports digitally control 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 +27 dBu (at 0dB gain and +17V supplies) in combination with the 1570/1583 without an input pad. The 5173 includes a differential servo and zero-crossing detector to minimize dc offsets and glitches (zipper noise) during gain adjustments.

The 5173 is controlled via an industry standard serial-peripheral interface (SPI) port. Four General Purpose Outputs (GPOs) can be controlled via this interface. The GPOs may be used to control auxillary functions such as input selectors, filters, mutes, LEDs, relays, etc.

The 5173 was designed to mate perfectly with the THAT 1570 or 1583 Differential Audio Preamplifier ICs. Together, the 1570/5173 or 1583/5173 combination provides a high performance solution for digitally-controllable audio preamplifier applications. However, the 5173 may also be used to control a discrete preamplifier.
