| 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. The HT813D0 p... |
