The C8051F350/1/2/3 devices include two 8-bit current-mode Digital-to-Analog Converters (IDACs). The
maximum current output of the IDACs can be adjusted for four different current settings; 0.25 mA, 0.5 mA,
1 mA, and 2 mA. The IDACs can be individually enabled or disabled using the enable bits in the corre-
sponding IDAC Control Register (IDA0CN or IDA1CN). An internal bandgap bias generator is used to gen-
erate a reference current for the IDACs whenever they are enabled. IDAC updates can be performed on-
demand, scheduled on a Timer overflow, or synchronized with an external pin edge. Figure 6.1 shows a
block diagram of the IDAC circuitry.
