Description
The M62364 is a CMOS 8-bit 8ch 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 1.0 mA 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.
