• Manufacturer: ROHM Co. Ltd.

●Equivalent Circuits
●Standard Example Application Circuit
●Operation Notes
＊1 25kΩ at Vcc = 5.0V (changes according to voltage supplied)
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).
This IC can select to decode the 10bit DI data pattern using either LSB first or MSB first, depending on the conditions of the
REVERSE terminal. Therefore, be sure to stabilize the REVERSE terminal by leaving it open or short-circuiting VDD (LSB
first), or short-circuiting GND (MSB first).
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.
