TLC5620 DAC conversion of the experimental procedure experimental procedure TLC5620 in the use of A, B, C, D four channels of the first two-channel output, respectively, the same cycle, ranging from 3.3V all the triangular wave and square wave, after 5620 the output of LM358 dual-Yun After the RP side to follow with enhanced load capacity and make the output signal voltage-3.3V ~ 0V located between the simulation has played a role in RP. In the proceedings, RNG bit enables the output bit rate of home doubled.
