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

o 0V to 10V absolute-voltage output supported

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

operation

? Support for extra regulation by external transistor, for

example JFET

? Programmable 24-bit sensor-signal-conditioning

math core

? Reprogrammable, nonvolatile memory (NVM)

? Programmable measurement scheduler for

continuous sensing applications, with optimized

balance of

o Energy consumption

o Output update rate

o Sensor-signal-conditioning accuracy

o Self-diagnostic coverage and system safety

? On-chip diagnostics:

o Sensor connection

o Broken-chip-check / chipping-check

Memory integrity
