R2A20178NP 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 municate 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...
