FSO @ -50 to 150°C)
Single pass calibration – quick and precise
Suitable for battery-powered applications
Small SOP8 package
Brief Description
The RBic
Lite
™ is a CMOS integrated 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 and offset or bridge linearity.
RBic
Lite
™ communicates via ZMD’s ZACwire
TM
serial
interface to the host computer and is easily mass
calibrated in a Windows
®
environment. Once cali-
brated, the output SIG™ pin can provide selectable 0
to 1V, rail-to-rail ratiometric analog output, or digital
serial output of bridge data with optional temperature
data.
Development Kit available
Multi-Unit Calibrator Kit available
Support for industrial mass calibration available
Quick circuit customization possible for large
production volumes
