M62364FP
8-BIT 8-CH MULTIPLYING D-A CONVERTER WITH BUFFER AMPLIFIERS
GENERAL DESCRIPTION
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.
FEATURES
• Three-wiring serial data transmission
• Doubled precision 8-ch D/A converter employing an R-2R with higher-order segment method
• 8 buffer amplifiers operating in a whole supply voltage range from VDD to GND
• 4-quadrant multiplication
APPLICATION
Digital to analog conversion for consumer and industrial equipment. Gain setting and automatic adjustment of display-monitor and CTV.

Function
Serial data input Serial data output
Shift clock input. Input data of DI are taken into the 12-bit shift register on a rising edge of the clock.
A low state enables data loading to the 12-bit shift register. During a rising edge of LD, the data will be loaded to the output register.
