Brief Description
The ZSSC3015 RBicdLite-Auto™ 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.
FEATUREs
● Digital compensation of sensor offset, sensitivity,
temperature drift, and nonlinearity
● 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, ZACwire™ digital one-wire interface
● Fast power-up to data out response; output
available 5ms after power-up
● Current consumption depends on programmed
sample rate and mode: 1mA down to 300µA (typ.)
● Fast response time: 1.4ms typical
● High voltage protection: ≤ 30V with external JFET
● AEC-Q100 qualified
