Note: 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 10 µF) should be connected between
RESET pin and ground to remove noise due to installation of line, etc.
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 (10 µF 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.
