TC94A04AFDG

TC94A04AFG/AFDG TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC94A04AFG,TC94A04AFDG 1 chip Audio Digital Processor TC94A04AFG/AFDG 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. TC94A04AFG Features Incorporates a 4 ch-stereo analog switch for AD converter input. Incorporates a 1 ch stereo line-out. Incorporates a 1 bit Σ ∆-type AD converter (two channels). THD: −82dB (typ.) S/N: 95dB (typ.) Incorporates a 1 bit Σ ∆-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. P-QFP80-1420-0.80M P-QFP60-1414-0.80N TC94A04AFDG Weight P-QFP60-1414-0.80N : 1.08 g (typ.) P-QFP80-1420-0.80M: 1.57 g (typ.) Incorporates a boot ROM to set a coefficient automatically, which enables to transfer an initial data from built-in ROM/RAM to registers at the time of resetting Boot ROM: 512 words The DSP block specifications are as follows: Data bus: 2...
