Usage Notes
1. With this IC, D-A converter upper reference voltage setting is performed by means of the power supply voltage. If
ripples or spikes are imposed on this pin, conversion accuracy may fall. When using this IC, a capacitor must be
inserted between the power supply pin and GND in order to ensure stable D-A conversion.
2. The output buffer amps of this IC are highly tolerant of capacitive loads. Therefore, connecting capacitors (0.1
µF
max.) between the output pins and ground in order to eliminate jitter or noise due to output line wiring presents no
problems whatever in terms of operation.
