M62368GP
3V TYPE 8-BIT 6CH D-A CONVERTER WITH BUFFER AMPLIFIERS
DESCRIPTION
The M62368GP is a CMOS semiconductor IC, containing 6
channels of 8-bit D-A converters. 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,and therefore is suitable for automatic control in
combination with a microcomputer.
FEATURES
•Operable with a low voltage between 2.7~3.6V
•12-bit serial data input(connected via 3 pins:DI,CLK,LD)
•6 channels of R-2R and segment type high-performance 8-bit
D-A converters
•6 buffer operational amplifiers with full swing of output voltage
between Vcc and GND.
•High oscillation stability against the capacitive load of buffer
operational amplifiers.
