ZSC31015
RBicdLite™ Analog Output Sensor Signal Conditioner w/ Diagnostic Features
Brief Description
Benefits
The ZSC31015 is adjustable to nearly all piezoresistive 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.

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
The digital one-wire interface (OWI) can be used for
a simple PC-controlled calibration procedure to program 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.*

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
