THAT5173 IC delivers 0dB to 60dB gain in 3dB steps, accepts up to +27.5dBu
THAT Corporation announced the latest addition to its best-in-class IC product line – the THAT5173 digital gain controller, a cost-effective, high-quality solution for digitally-controlled audio preamplifier applications.
Accepting full pro-audio signal levels up to +27.5dBu without an input pad, the 5173 maintains exceptional performance over a wide range of gains and signal levels. Thanks to its advanced design and integrated DC servo amplifier, the 5173 provides click-less digital gain control for differential analog current-feedback preamplifiers. The small 5mm × 5mm 5173 controls gain from 0dB to 60dB in 3dB steps, with low noise and distortion.
The 5173 is designed to operate seamlessly with the THAT1570 high performance current-feedback amplifier, THAT's state-of-the-art analog differential microphone preamp. In combination with the 1570, the 5173 operates with supplies from ±5V to ±17V. Its differential output is ideal for connection to high-performance, differential-input A/D converters.
The THAT5173 digital gain controller is targeted for high performance digitally-controlled preamplifiers, either as standalone products, or within audio mixing consoles, PC-audio breakout boxes, and instrumentation amplifiers. The IC comes in a QFN24 package. It features a wide gain range of 0 to 60dB in 3dB steps, a supply range of ±5V to ±17V, an output and input swing of up to +27.5dBu (± 17V supply) and a low 1kHz THD under 0.001% for gains up to 42dB.
