OPERATION-D/ACONVERTER
The TSC2300 has an onboard 8-bit D/A converter, configured as shown in Figure 70. This configuration yields a
current sink (AOUT) controlled by the value of a resistor connected between the ARNG pin and ground. The D/A
converter has a control register, which controls whether or not the converter is powered up. The eight-bit data is written
to the D/A converter through the D/A converter data register.
