HT815D0 11.2-Second LOG-PCM Speech

The HT815D0 is a single chip LOG-PCM voice synthesizer LSI with 11.2-second voice capacity at 6kHz sampling rate. The chip when triggered drives a speaker through an external transistor with a current switch D/A converter output. Negligible current will be consumed in the standby state. The HT815D0 .
