1 chip Audio Digital Processor
TC94A04AF/AFD is a single-chip audio Digital Signal Processor,
incorporating 4 way stereo analog switch, 2 ch AD converter, 4 ch
DA converter, and electronic volume for trimming.
It is possible to realize many applications, such as sound field
control -hall simulation, for example-, digital filter for equalizers,
surround, base boost and something.
TC94A04AF
Features
Incorporates a 4 ch-stereo analog switch for AD converter
input.
Incorporates a 1 ch stereo line-out.
Incorporates a 1 bit
∑ ∆-type
AD converter (two channels).
THD:
−82dB
(typ.) S/N: 95dB (typ.)
Incorporates a 1 bit
∑ ∆-type
DA converter (four channels).
THD:
−86dB
(typ.) S/N: 98dB (typ.)
Incorporates a trimming analog volume for each output of DA
converter. 0dB to
−24dB
(1dB step)
As digital input/output port, this has 3 input port (6 ch) and 1
output port (2 ch), enabling input/output of sampling of 96
kHz/24 bit.
Incorporates a built-in digital de-emphasis filter.
Incorporates a digital attenuator.
