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.

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 V

• High oscillation stability against the capacitive load of buffer operational amplifiers

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).
