M62368GP 3 V Type 8-bit 6ch D/A Converter with Buffer Amplifiers REJ03D0878-0201 Rev.2.01 Dec 27, 2007 Description The M62368GP is a CMOS semiconductor IC, containing 6 channels of 8-bit D/A converters. It is operable with a low supply voltage between 2.7 to 3.6 V, and is easy to use due to serial data input, and 3-pin (DI, CLK, LD) connection with microcomputer. The IC also contains DO pin terminal, enabling cascade connection, and therefore is suitable for automatic control in combination with a microcomputer. Features • • • • • Operable with a low voltage between 2.7 to 3.6 V 12-bit serial data input (connected via 3 pins: DI, CLK, LD) 6 channels of R-2R and segment type high-performance 8-bit D/A converters 6 buffer operational amplifiers with full swing of output voltage between VCC and GND High oscillation stability against the capacitive load of buffer operational amplifiers Application Digital/analog conversion in industrial or home-use electronic equipment.
