Brief Description
The ZSSC3008 is a sensor signal conditioner IC that is adjustable to nearly all piezo-resistive bridge sen-sors. Measured and corrected bridge values are pro-vided at the SIG™ pin, which can be configured as an analog voltage output or as a one-wire serial dig-ital output.
The digital one-wire interface (OWI) can be used for a simple PC-controlled calibration procedure to pro-gram a set of calibration coefficients into an on-chip EEPROM. The calibrated ZSSC3008 and a specific sensor are mated digitally: fast, precise, and without the cost overhead associated with trimming by exter-nal devices or laser. Integrated diagnostics functions make the ZSSC3008 particularly well-suited for auto-motive applications.

Features
Digital compensation of sensor offset, sensitivity, 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
Output options: rail-to-rail ratiometric analog voltage (12-bit resolution), absolute analog voltage, digital one-wire interface
Fast power-up to data out response; output available 5ms after power-up
Current consumption depends on programmed sample rate: 1mA down to 250㎂ (typical)
Fast response time: 1ms (typical)
High voltage protection up to 30V with external JFET
