ZSSC3240
Sensor Signal Conditioner IC for Resistive Sensors
Datasheet
Description
The ZSSC3240 is a sensor signal conditioning IC
(SSC) for highly accurate amplification, digitization,
and sensor-specific correction of resistive sensor
signals. The ZSSC3240 is suitable for bridge and
half-bridge sensors, as well as external voltage-
source element and single-element sensors (e.g.,
Pt100 and external temperature sensor diodes)
powered by an on-chip current source. Digital
compensation of the sensor offset, sensitivity,
temperature drift, and non-linearity is accomplished
via a 26-bit math core running a correction algorithm
with calibration coefficients stored in a non-volatile,
reprogrammable memory. The programmable,
integrated sensor front-end allows optimally applying
various sensors for a broad range of applications.
The ZSSC3240 provides measurement value
readouts and programming capabilities via an I2C,
SPI, or one-wire interface (OWI). Three different
operation modes allow optimal development of
digital, digital-analog, and analog-output smart
sensor modules including wake-up on request,
continuous-on/fast-response, and automatic/cyclic
sensor measurement operations. Absolute and
ratiometric voltage, current-loop, or interrupt analog
outputs are supported by the ZSSC3240. The
analog output options and digital interface options
(for calibration and/or a digital application interface)
can be combined.
