General Description
The HT813D0 is a single-chip LOG-PCM voice synthesizer LSI with 5.6-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.
Key Features
