M62361FP Datasheet | Mitsubishi Electric

MITSUBISHI<Dig.Ana.INTERFACE> 8-BIT 6CH D-A CONVERTER WITH BUFFER AMPLIFIERS 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 microputer. This IC is designed to be operable when chip select data contained in the 15-bit data conforms to the state of the CS terminal.Accordingly,the IC can process data by strobe signals mon with other devices connected to the bus of microputer, and does not involve an microputer 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.
