Milford, MA (March 14, 2012)—THAT Corporation has added the 5173 digital gain controller to its IC product line.
The 5173 reportedly accepts full pro-audio signal levels up to +27.5 dBu without an input pad. According to the company, due to its design and integrated DC servo amplifier, the 5173 provides “click-less digital gain control for differential analog current-feedback preamplifiers.” The 5mmx5mm 5173 controls gain from 0 dB to 60 dB in 3dB steps.
The 5173 is designed to operate with the THAT1570 current-feedback amplifier, the company’s analog differential microphone preamp. In combination with the 1570, the 5173 operates with supplies from ±5V to ±17V. Its differential output can be used for connection to differential-input A/D converters.
“The 5173 is the first significant extension to our existing line of digitally controllable preamplifiers,” says Les Tyler, president, THAT Corporation. “Customers who require the ultimate in performance will select the 5171/1570 combination, while those who are more cost-conscious will find the 5173/1570 strikes an appropriate balance between cost and performance. The 3 dB steps are appropriate for many mic preamp applications, and by accepting full pro audio levels without a pad, the 5173 saves space over other approaches.”
