audio preamplifiers such as the THAT 1570.

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 combi-

nation with the 1570 -- without an input pad. The

small (5x5 mm) 24-pin QFN package, making it

suitable for small portable devices.
