... GENERAL DESCRIPTION MSM9831 is a PCM-based Voice Synthesis LSI (Playback only) with on-chip 384 Kbit Mask ROM, D/A Converter and Low-Pass Filter. Serial input interface for an external MCU makes MSM9831 a better choice for size-critical applications with less wiring pin-count in small foot-print packaging. FEATURES ...

... In the mid-range of waveform, OKI 8-bit non-linear PCM has precision equivalent to that of 10-bit straight PCM. Inserting Silence In addition to normal recorded sound phrases, the MSM9831 allows a user to play back or insert silence (silent phrase). User can set up time length of silence from a minimum of 32ms to a maximum of 996ms in 32ms step when f =4 ...

... CONNECTING THE MSM9831 TO SPEAKER DRIVING AMPLIFIER The MSM9831 uses a current output type D/A converter. When the MSM9831 is connected to a voltage input type amplifier required to convert the voice signal that is output as "change of current" into the voice signal that is output as "change of voltage". The connection between the MSM9831 and MSC1157 (OKI speaker driving amplifier) when a resistor is used for the above conversion is described below ...

... Therefore, the voice output circuit of the MSM9831 is different from that of the MSM6650 family product which has employed a voltage output type D/A converter. The voice output circuit of the MSM9831 also is different from that of the MSM9800 family product because the MSM9831 has employed a current flowing-in type D/A converter and the MSM9800 family product has employed a current flowing-out type D/A converter ...
