Overview

Product details

XL549 is an 8-bit serial A/D converter chip, which adopts CMOS technology and realizes A/D conversion by 8-bit switching capacitor successive approximation method. It can be serial interface with general microprocessor and controller through CLK, CS and DATAOUT, and constitute a variety of cheap measurement and control application systems. With a 4MHz on-chip system clock and hardware and software control circuit, the conversion time is up to 17μs, and the XL549 sampling is 40,000 times /s. The maximum total out-of-balance error of other functions is ± 0.5LSB, and the typical power consumption is 6mW. Differential reference voltage high resistance input, anti-interference, can be calibrated according to the proportional scale conversion range, VREF+-VREF-≥1V, can be used for small signal sampling.
