M62371GP
3 V Type 8-bit 36ch Selector SW Built-in D/A Converter with Buffer Amplifiers
REJ03D0880-0201 Rev.2.01 Dec 27, 2007

Description
The M62371GP is a CMOS semiconductor IC, containing 36 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. (M62371GP is an advanced product of M62370GP on its buffer amp. drivability.)

Features
Operable with a low voltage between 2.7 to 3.6 V 16-bit serial data input (connected via 3 pins: DI, CLK, LD) 36 channels built-in of 8-bit D/A converter 6 channels of D/A converters capable of selecting and outputting 4 data stored in each converter, through 2 control terminals

Application
Digital/analog conversion in industrial or home-use electronic equipment. Automatic control in combination with EEPROM and microcomputer (Substitute for conventional semi-fixed resistor).
