Description
The M62367GP is a CMOS semiconductor IC has 8 channels of 8-bit D/A converter. 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.
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)
• 8 channels of R-2R and segment type high-performance 8-bit D/A converters
• 8 buffer operational amplifiers with full swing of output voltage between V_CC and GND
• 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).
