Technical Note
1(E) 1(O) 2(E) 2(O)
When the start pulse (SFTR, SFTL) is input two times, the data is sampled based on the second start pulse.
●Power Supply Sequence
Maintain the following power supply order to prevent the device from being destroyed.
Turn on power order : DV_DD → Input signal → AV_DD, V0~V15
Turn off power order : AV_DD, V0~V15 → Input signal → DV_DD
DV_SS, AV_SS
AV_DD
V0～V15

●Notes for use
1. When power is first supplied to the CMOS IC, it is possible that the internal logic may be unstable and rush current may
flow instantaneously.
Therefore, give special consideration to power coupling capacitance, power wiring, width of GND wiring, and routing of
connections.
2. For ICs with more than one power supply, it is possible that rush current may flow instantaneously due to the internal
powering sequence and delays.
Therefore, give special consideration to power coupling capacitance, power wiring, width of GND wiring, and routing of
wiring.
