Description

The TC9470FN is a second-order - modulation system 1-bit DA converter incorporating an 8-times oversampling digital filter, dynamic digital bass boost function for use with compressor operations and an analog filter developed for digital audio equipment.

Because the TC9470FN IC includes an analog filter, it can output a direct analog waveform, thus reducing the size and cost of the DA converter.
