ZMD31015
RBicdLite™ Low-Cost Sensor Signal Conditioner with Diagnostics
Brief Description
Benefits
The RBicdLite™ 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 onewire serial digital output.

No external trimming components required

PC-controlled configuration and calibration via
one-wire interface – simple, low cost

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 onchip EEPROM. The calibrated RBicdLite™ 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 RBicdLite™ 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
