API8108A General Description
API8108A is a high quality voice synthesizer capable of varying playback duration. A proprietary ADPCM algorithm is used. The audio message is stored in a 256K bits on chip EPROM which can store up to ten seconds of voice data at 6 KHz sample rate.
The API8108A eliminates the need of complicated circuitryeplus.g in voice playback but still achieves high voice quality.deprevie Sounds such as human speech, animal sounds, musical sounds and even special sound effects can be synthesized. Versatile combinations in sections achieve longer playbackr duration. In addition, devices can be cascaded to achieveencentT longer voice duration. Two devices can be configured in parallel in order to achieve signal mixing without an external mixer in which speech can be mixed with background music each from one of two different chips.
The API8108A provides wide operating voltage rangeN feom 2.8Vto6.0V.PWM digital amplifier output pins,VOUT1 and VOUT2 provides direct drive to buzzer or speaker.
A current output pin, COUT, enables the device to drive aJPLNDMP 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.
