Brief Description

The ZSC31015 is adjustable to nearly all piezo-

resistive bridge sensors. Measured and corrected

bridge values are provided at the SIG™ pin, which

can be configured as an analog voltage output or as

a one-wire serial digital output.

The digital one-wire interface (OWI) can be used for

a simple PC-controlled calibration procedure to prog-

ram a set of calibration coefficients into an on-chip

EEPROM. The calibrated ZSC31015 and a specific

sensor are mated digitally: fast, precise, and without

the cost overhead associated with trimming by

external devices or laser. Integrated diagnostics

functions make the ZSC31015 particularly well

suited for automotive applications.*

Features

 Digital compensation of sensor offset, sensitivity,

temperature drift, and non-linearity

 Programmable analog gain and digital gain;

accommodates bridges with spans < 1mV/V

and high offset

 Many diagnostic features on chip (e.g., EEPROM

signature, bridge connection checks, bridge short

detection, power loss detection)

 Independently programmable high and low

clipping levels

 24-bit customer ID field for module traceability

 Internal temperature compensation reference

(no external components)

 Option for external temperature compensation

with addition of single diode

 Output options: rail-to-rail ratiometric analog

voltage (12-bit resolution), absolute analog

voltage, digital one-wire interface

 Fast power-up to data out response; output

available 5ms after power-up

 Current consumption depends on programmed

sample rate: 1mA down to 250

A (typical)

 Fast response time: 1ms (typical)

 High voltage protection up to 30V with

external JFET

Benefits

 No external trimming components required

 Simple PC-controlled configuration and

calibration via one-wire interface

 High accuracy: ±0.1% FSO @ -25 to 85°C;

±0.25% FSO @ -50 to 150°C

 Single-pass calibration

– quick and precise

Available Support

 Evaluation Kit available

 Mass Calibration System available

 Support for industrial mass calibration available

 Quick circuit customization possible for large

production volumes

Physical Characteristics

 Wide operation temperature:

–50°C to +150°C

 Supply voltage 2.7 to 5.5V; with external JFET,

5.5 to 30V

 Small SOP8 package
