Microphone Gain Controllers

THAT's Digital Gain Controllers have been designed to work best with their range of high performance Preamplifiers to add the functionality that users expect in modern audio equipment.

Separating the Preamplifier into a digital and analogue section has the advantage of being able to mix and match parts to best suit your design goals, at the lowest price point. The two chip solution still uses less pcb space and draws less power than the PGA2500 single chip. THAT's wider signal range means that more of the microphones dynamic range can be captured for the rest of the signal chain.

A neat feature is the zero crossing sync output which enables the dsp to coordinate gain changes as well, ideal for finer resolutions.
