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 D_O 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).
