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. DV
DD
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 DV
.
DD
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 AV
and DV
pins share the same power supply on a board to prevent latch-up which may
DD
DD
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.
