All rights reserved. ● Equivalent Circuits *1: 25kΩ at Vcc = 5.0V (changes according to voltage supplied) ● Standard Example Application Circuit ● Operation Notes Ensure that a constant voltage is supplied to each of the 1 ground and 3 power supply terminals. Insert a bypass capacitor between each power supply terminal and ground in order to prevent deterioration of the D/A conversion accuracy due to ripple and noise signals. A capacitor should be inserted between the output and ground in order to eliminate jitter and noise. A capacitance up to 100pF is recommended (including the capacitance of the wire). Inserting a capacitor between the RESET terminal and GND and utilizing a time constant enables power ON reset functionality. Furthermore, when inputting the reset signal from the controller, it is possible to fix the output of all channels to Low at the low area of pulse. 1 to inside 2 to inside *1 3 from inside 4 ・ 5 ・ 6 4 5 6 AO 1 AO 2 AO 3 VrefH VrefL VC C GN D AO 6 DI CLK LD C ontroller CH 1 CH 2 CH 3 CH 6 Reset |
