Tone Dialer with Built-in Piezo Driver

OVERVIEW The SM8230A is a dual-tone signal generator LSI developed for DTMF (dual tone multi-frequency) dialing. It features a built-in piezo-electric speaker driver for direct connection to a piezo-electric buzzer. The DTMF frequencies can be set to correspond to the DTMF standards of any count
