o Voltage source
 On-chip temperature sensor
 External temperature sensing supported, e.g.
sensor-bridge as temperature detector, external
diode, etc.
 Support for Pt100
 Programmable 16-bit digital-to-analog-converter and
output:
o (0V to 1V) or (0V to 5V) absolute voltage output
o VDD-ratiometric voltage output
o 4mA to 20mA current-loop output supported
o 0V to 10V absolute-voltage output supported
 On-chip voltage regulators for sensor supply, and IC
operation
