2. Power supply
To prevent the influence of noise, connect the power supply to a 0.1µF by-pass capacitor as near the device
as possible.
3. DVDD
Either a 3.3V or 5.0V digital power supply can be used. Compared to the 5.0V power supply, the 3.3V power
supply generates a decreased amount of radiation noise but offers a decreased drive capacity. These two
power supplies do not virtually differ in static and dynamic characteristics. Further, the High output level rises
up to DVDD.
4. Reference input
The voltage to be supplied to the reference pins must be driven by a buffer having a 10mA or more drive
capacity. For supplied voltage stabilization, connect the buffer to a 0.1µF by-pass capacitor as near the pins as
possible.
5. Latch-up
Ensure that the AVDD and DVDD pins share the same power supply on a board to prevent latch-up which may
be caused by power ON time-lag.
6. Board
To obtain full-expected performance from this IC, be sure that the mounting board has a large ground pattern
for lower impedance. It is recommended that the IC be mounted on a board without using a socket to evaluate
its characteristics adequately.
