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
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.
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
operational amplifiers.
APPLICATION
Adjustment/control of industrial or home-use electric
equipment,such as VTR camera,VTR set,TV,and CRT
display.
