M62353GP

Preliminary Datasheet M62353P/FP/GP 8-bit 8ch D/A Converter with Buffer Amplifiers R03DS0042EJ0400 Rev.4.00 Jun 03, 2011 Description The M62353 is an integrated circuit semiconductor of CMOS structure with 8 channels of built-in D/A converters with output buffer operational amplifiers. The 3-wire serial interface method is used for the transfer format of digital data to allow connection with microcomputer with minimum wiring. It is able to cascading serial use with DO terminal. The output buffer operational amplifier operates in the whole voltage range from power supply to ground for both input/output. Features  12-bit serial data input (3-wire serial data transfer method)  Highly stable output buffer operational amplifier allow operation in the all voltage range from power supply to ground. Application Adjustment/control of industrial or home-use electronic equipment, such as VTR camera, VTR set, TV, and CRT display.
