TC9444F TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC9444F Single-Chip karaoke IC II The TC9444F is a karaoke chip for such applications as equipment for CD/LD players, mini component stereo sets, radio-cassette players, and VTRs. With its internal AD/DA converter system, the TC9444F can offer such karaoke functions as echo, vocal canceling, and key control on a single chip in addition to such digital signal processing (DSP) features as sound field control and bass/treble control. Because the program and coefficients are stored on internal ROM, the IC can be controlled by simple settings. Features · THD: −65dB · S/N ratio: 80dB (typ.) Weight: 1.08 g (typ.) Incorporates an AD converter (three channels) with 2 times oversampling.
