GENERAL DESCRIPTION
The ML2216-XXX is speech synthesis device with a 8Mbit P2ROM built-in. The ML2216-XXX incorporates ADPCM2 decoder, 12-bit D/A converter, and low-pass filter. Moreover, the monophonic speaker amplifier for driving a direct speaker is built in. The ML2216-XXX carried out all functions required for a voice response circuit to one chip. For this reason, inclusion to small and pocket equipment became still easier.
