... Flexible, addressable SPI interface Four general-purpose digital outputs Small 7mm x 7mm QFN32 package The THAT5171 is a digital gain controller for low-noise, analog, differential, current-feedback audio preamplifiers such as the THAT 1570. When used in conjunction with an appropriate analog gain block, the 5171 can set gain to 5 ...

... THAT5171 High-Performance Digital Preamplifier Controller IC The THAT 5171 is a gain controller in the form of a digitally controlled differential attenuator not an amplifier. It contains a set of precision resistors, switched by a set of CMOS FET switches, configured to create a variable, switched, differential attenuation network. The network’s impedances are ideal for ...

... THAT5171 High-Performance Digital Preamplifier Controller IC While the servo is effective at minimizing dc offset at the outputs, it does require time to react. When gain is changed, particularly if a sudden large increase in gain is initiated (e.g., 5.6dB to 68.6dB), the servo output will not change instantaneously with the gain change. Immediately after the gain increase, ...
