1.9.
The C8051F330 and C8051F330D 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 pro-
vided, allowing IDA0 output updates on a write to IDA0H, on a Timer overflow, or on an external pin edge.
