ZMD31010
RBicLite™ Low-Cost Sensor Signal Conditioner
Brief Description
Benefits
The RBicLite™ ZMD31010 is a sensor signal condi-
tioner integrated circuit, which enables easy and pre-
cise 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 RBicLite™ communi-
cates via ZMD’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.
