Serial 13-Bit Linear Codec (A/D and D/A)

The MC145402 is a 13–bit linear monotonic digital–to–analog and analog–to–digital converter implemented in a single silicon–gate CMOS IC. Potential applications include analog interface for Digital Signal Processor (DSP) applications, high speed modems, telephone systems, SONAR, Adaptive Differential Pulse Code Modulation (ADPCM) converters, echo cancellers, repeaters, voice synthesizers, and music synthesizers.
