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.The built-in buffer operational amplifiers are of full-swing
design with a wide operating supply voltage range for input/output
voltage.In addition,this IC provides improved stability against a
capacitive load,and therefore is suitable for application to electronic
volume(VCA)control,substitute for adjustment semi-fixed
resistor,etc.

M62366GP

3V TYPE 8-BIT 12CH D-A CONVERTER WITH BUFFER AMPLIFIERS

DESCRIPTION

The M62366GP is a CMOS semiconductor IC,containing 12
channels of 8-bit D-A converters,with a high-performance buffer
operational amplifier provided in the output of each channel. It is
operable with a low supply voltage between 2.7~3.6V,and is easy

FEATURES

•Operable with a low voltage between 2.7~3.6V

•12-bit serial data input(connected via 3 pins:DI,CLK,LD)

•12 channels of R-2R and segment type high-performance 8-bit
D-A converters

•12 buffer operational amplifiers with full swing of output voltage
between Vcc and GND.

•High oscillation stability against the capacitive load of buffer

APPLICATION

Adjustment/control of industrial or home-use electric

equipment,such as VTR camera,VTR set,TV,and CRT

Function
Serial data input terminal to input 12-bit long serial data
Terminal to output MSB data of 12-bit shift register

Shift clock input terminal.Input signal at DI pin is input to 12-bit shift register at rise of shift clock pulse

When H-level signal is input to this terminal,the value stored in 12-bit shift register is loaded
in decoder and D-A converter output register

8-bit D-A converter output terminal

Power supply terminal

GND terminal

D-A converter upper reference voltage input terminal
