PRECAUTION FOR USE
This IC has two power supply pins and a ground pin.
Superimposition of these pins with ripple and spike noise may
cause reduction of conversion accuracy and occurrence of
malfunction. Be sure to insert a capacitor between each power
supply and the GND pin to stabilize D-A converting operation.
The output buffer amplifier of this IC has strong characteristics
against capacitive load. Accordingly, when the capacitance (10µF
MAX.) is connected between output and ground to remove jitter
and noise due to installation of output line, no problem may occur
in operation of DAC. However, notice that the removal results in
lengthening the settling time.
This IC also provides power-on reset function. To assure the
resetting operation, power supply should be turned on in the order
of timing shown in the diagram below.
(Order): 1. VCC 2. VDD

(*) The RESET pin is directly connected with the power pin to
use power-on reset. However, when forced reset is done
from outside, the capacitance (0.1 to 10µF) should be
connected between RESET pin and ground to remove noise
due to installation of line, etc.
