M8031-2S : DING-DONG SOUND EFFECT GENERATOR IC
_________________________________________________________________________________
General Description
The M8031-2S is a ding-dong sound effect generator IC produced by LSI CMOS technology. With
built-in RC oscillator and digital envelope circuits, minimal external components are required. This IC
simulates the mechanical ding-dong sound, and is ideal for door bell application.
Features
- 1.3V to 3.3V operating voltage and low power consumption
- One-shot mode of 2 ding-dong playing sequences
-
Standard TO-92 package form
- Dynamic speaker can be driven with external NPN transistor
