Description
The M62364FP 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 V_DD to GND.
The IC is suitable for a use in automatic adjustment applications in conjunction with a MCU by utilizing the terminal
D_O for a cascading connection.
Features
• Three-wiring serial data transmission
• Doubled precision 8ch D/A converter employing an R-2R with higher-order segment method
• 8 buffer amplifiers operating in a whole supply voltage range from V_DD 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.
