Features

• Digital communication and calibration interfaces

o SPI up to 10MHz

o I2C (Standard, Fast, and High-Speed Mode)

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, 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

• On-chip voltage regulators for sensor supply, and IC

operation

• Support for extra regulation by external transistor, for

example JFET
