ZSSC3240

Sensor Signal Conditioner IC for Resistive Sensors

Description

Features

The ZSSC3240 is a sensor signal conditioning IC

(SSC) for highly accurate amplification, digitization,

and sensor-specific correction of resistive sensor

signals. The ZSSC3240 is suitable for bridge and

half-bridge sensors, as well as external voltage-

source element and single-element sensors (e.g.,

Pt100 and external temperature sensor diodes)

compensation of the sensor offset, sensitivity,

temperature drift, and non-linearity is accomplished

via a 26-bit math core running a correction algorithm

with calibration coefficients stored in a non-volatile,

reprogrammable memory. The programmable,

integrated sensor front-end allows optimally applying

various sensors for a broad range of applications.

 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.

The ZSSC3240 provides measurement value

readouts and programming capabilities via an I2C,

SPI, or one-wire interface (OWI). Three different

operation modes allow optimal development of

digital, digital-analog, and analog-output smart

sensor modules including wake-up on request,

continuous-on/fast-response, and automatic/cyclic

sensor measurement operations. Absolute and

ratiometric voltage, current-loop, or interrupt analog

outputs are supported by the ZSSC3240. The

analog output options and digital interface options

(for calibration and/or a digital application interface)

can be combined.

 Support for Pt100

 Programmable 16-bit digital-to-analog-converter and

output:

o (0V to 1V) or (0V to 5V) absolute voltage output

o V_DD-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
