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.
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
•12 buffer operational amplifiers with full swing of output voltage
•High oscillation stability against the capacitive load of buffer
APPLICATION
operational amplifiers.
equipment,such as VTR camera,VTR set,TV,and CRT
display.
Adjustment/control of industrial or home-use electric
The IC also contains Do pin terminal,enabling cascade
D-A converters
between Vcc and GND.
