• Digital communication and calibration interfaces:
o SPI up to 10MHz
o I2C (Standard, Fast, Fast+) and I3C SDR
o One-wire-interface (OWI), up to 100kBit/s
• Accommodates nearly all resistive bridge sensor
types (signal spans from 1mV/V up to 500mV/V)
• Supports different sensor element configurations:
o Resistive bridge or half-bridge
o Resistive divider string
o Voltage source
• On-chip temperature sensor
• External temperature sensing supported, for
example, sensor-bridge as temperature detector,
external diode, etc.
• Programmable 16-bit digital-to-analog-converter
and output (supporting “True-0Volt”-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
• Wide operational temperature and supply range
• On-chip voltage regulators for sensor supply, and IC operation
• Support for extra regulation by external
transistor, for example, JFET (especially for
industrial supply voltages >5.5VDC)
• Programmable sensor-signal-conditioning math core
• Reprogrammable, nonvolatile memory (NVM)
• On-chip diagnostics:
o Sensor connection
o AFE self-test
o Memory integrity
