Datasheet
Brief Description
The ZSC31010 is a sensor signal conditioner inte-
grated circuit, which enables easy and precise
calibration of resistive bridge sensors via EEPROM.
When mated to a resistive bridge sensor, it will
digitally correct offset and gain with the option to
correct offset and gain coefficients and linearity over
temperature. A second-order compensation can be
enabled for temperature coefficients of gain or offset
or bridge linearity. The ZSC31010 communicates via
IDT’s ZACwire™ serial interface to the host
computer and is easily mass calibrated in a
Windows® environment. Once calibrated, the output
pin Sig™ can provide selectable 0 to 1 V, rail-to-rail
ratiometric analog output, or digital serial output of
bridge data with optional temperature data.
Features
Digital compensation of sensor offset, sensitivity,
temperature drift, and non-linearity
Accommodates differential sensor signal spans,
from 3 mV/V to 105 mV/V
ZACwire™ One-Wire Interface (OWI)
Internal temperature compensation and detection
via bandgap PTAT (proportional to absolute
temperature)
Output options: rail-to-rail analog output voltage,
absolute analog voltage, digital ZACwire™ One-
Wire Interface (OWI)
Optional sequential output of both temperature
and bridge readings on ZACwire™ digital output
Fast response time, 1 ms (typical)
High voltage protection up to 30 V with
external JFET
Chopper-stabilized true differential ADC
Buffered and chopper-stabilized output DAC
Benefits
No external trimming components required
Simple PC-controlled configuration and
calibration via ZACwire™ 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
Suitable for battery-powered applications
