HT2830 Description
The HT2830 is a CMOS LSI chip designed for use in sound effect products. It is a body structure including tone circuit, noise circuit, an updown counter, and other control logic to generate various sounds such as JET plane, motorcycle, helicopter, train, and so forth.
HT2830 Key Features
- Single power supply: 2.4V~3.3V Low standby current: 1µA (Typ.) at VDD=3V Speaker or direct piezo application Sound outpu
- Two direct LED drive outputs (The flash rate depends on the sound speed) Option mode selection: normal mode or auto mode
HT2830 Applications
- The IC substrate should be connected to VDD in the PCB layout artwork
