M62364FP
8-BIT 8-CH MULTIPLYING D-A CONVERTER WITH BUFFER AMPLIFIERS
GENERAL DESCRIPTION
PIN CONFIGURATION (TOP VIEW)
The M62364FP is a CMOS 8-bit, 8-ch D/A converter having a
multiplying function and output buffer amplifiers. It has a serial data
input and can easily communicate with a microcontroller by the
simple three-wiring method (DI, CLK, LD).
The output buffer amplifiers operating in AB-class has both sinking
and driving capabilities of 1.0mA or more and can operate in a whole
supply range from VDD to GND.
The IC is suitable for a use in automatic adjustment applications in
conjunction with a MCU by utilizing the terminal DO for a cascading
connection.
