AP8842 General Description
aP8821 is a high quality voice synthesizer capable of varying playback duration. A proprietary ADPCM algorithm is used. The audio message is stored in a 512K bits on-chip EPROM which can
store up to 21 seconds of voice data at 6 KHz sample rate.
The aP8821 eliminates the need of complicated circuitry in voice playback but still achieves high voice quality for different kind of sounds. Combinations in sections achieve longer playback duration.
A pair of PWM output pins, VOUT1 and VOUT2 provides direct drive to buzzer or speaker.
A current output pin, COUT, enables the device to drive a speaker through a low cost NPN transistor. No complex filtering or amplifier circuit is needed. An automatic ramp-down function eliminates undesired noise at the end of playback.
