Overview

The R2A20178 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 simple three-wiring method (DI, CLK, LD), and it is suitable for a use in automatic adjustment applications in conjunction with a MCU. The reference voltage terminals (VDAref1, VDAref2) are 4ch x 2 configuration, and the 4 quadrant operation is possible.

  • Guarantee Nonlinearity error : +/-1.0LSB, Differential nonlinearity error : +/-0.7LSB
  • Three-wiring serial data transmission
  • High performance 8ch 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
  • High anti-oscillation stability for capacitive loads
  • 4 quadrant multiplication
  • Very small package : QFN (pin pitch 0.5mm)
