DESCRIPTION
The M62361FP is a Bi-CMOS semiconductor IC,containing 6
channels of 8-bit D-A converters(DAC),with a buffer operational
amplifier provided in the output of each channel.It is easy to use
due to serial data input, and three-pin(DT,CK,ST)connection with
microcomputer.
contained in the 15-bit data conforms to the state of the CS
terminal.Accordingly,the IC can process data by strobe signals
common with other devices connected to the bus of
microcomputer, and does not involve an microcomputer port to
drive the IC.The inputs are connected to a level shift circuit so
that the input threshold level does not depend on supply
voltage.The IC also contains an initialization function to reset
output(0 scale)when power is turned ON or drops.
