ZSSC3015
RBicdLite-Auto™ Sensor Signal Conditioner with Diagnostics
Brief Description
Benefits
The ZSSC3015 sensor signal conditioner IC 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.

No external trimming components required

PC-controlled configuration and calibration via
ZACwire™ one-wire interface – simple, low cost

High accuracy (as high as ±0.1% FSO @ -25 to
85°C; ±0.25% FSO @ -50 to 150°C)

Single-pass calibration – quick and precise
The ZACwire™ 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 ZSSC3015
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 ZSSC3015 particularly well suited for automotive applications.
