C8051F330/1
Rev. 1.1 25
1.9. 10-bit Current Output DAC
The C8051F330 device includes a 10-bit current-mode Digital-to-Analog Converter (IDA0). The maximum current
output of the IDA0 can be adjusted for three different current settings; 0.5 mA, 1 mA, and 2 mA.
IDA0 features a
flexible output update mechanism which allows for seamless full-scale changes and supports jitter-free updates for
waveform generation. Three update modes are provided, allowing IDA0 output updates on a write to IDA0H, on a
Timer overflow, or on an external pin edge.
