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).
