1 / 26 page  Fast Automotive Sensor Signal Conditioner ZSC31150 Datasheet © 2016 Integrated Device Technology, Inc. 1 December 6, 2016 Brief Description The ZSC31150 is a CMOS integrated circuit for highly accurate amplification and sensor-specific correction of bridge sensor signals. Digital compensation of sensor offset, sensitivity, temperature drift, and non-linearity is accomplished via an internal 16-bit RISC microcontroller running a correction algorithm, with calibration coefficients stored in an EEPROM. The ZSC31150 is adjustable to nearly all bridge sensor types. Measured values are provided at the analog voltage output or at the digital ZACwire™ and I2C interface. The digital interface can be used for a simple PC-controlled calibration procedure in order to program a set of calibration coefficients into an on-chip EEPROM. A specific sensor and a ZSC31150 can be mated digitally: fast, precise, and without the cost overhead associated with trimming by external devices or a laser. Features Digital compensation of sensor offset, sensitivity, temperature drift, and non-linearity Adjustable to nearly all bridge sensor types Analog gain of up to 420 Output options: ratiometric analog voltage output (5% to 95% maximum, 12.4-bit resolution) or ZACwire™ (digital one-wire- interface) Temperature compensation: internal or external diode, bridge resistance, thermistor Sensor biasing by voltage or constant current Sample rate: up to 7.8kHz High voltage protection up to 33V Supply current: max. 5.5mA Reverse polarity and short-circuit protection Wide operation temperature depending on part number: up to -40°C to +150°C Traceability by user-defined EEPROM entries Safety and diagnostic functions Benefits No external trimming components required Only a few external protection devices needed PC-controlled configuration and single pass calibration via I2C or ZACwire™ interface: simple, cost efficient, quick, and precise End-of-line calibration via I2C or ZACwire™ interface High accuracy (0.25% FSO at -25 to 85°C; 0.5% FSO at -40°C to 125°C) Excellent EMC/ESD robustness and AEC-Q100 qualification Available Support Evaluation Kits Application Notes Mass Calibration System Physical Characteristics Supply voltage: 4.5V to 5.5V Operation temperature: -40°C to 125°C (-40°C to +150°C extended temperature range) Available as 14-DFN (5 4 mm; wettable flanks), SSOP14, and die ZSC31150 Application Circuit 2 1 3 4 6 5 7 14 13 12 11 10 8 Serial Interface Sensor Bridge SDA SCL Out / OWI GND VSUPP C3 47nF +4.5V to +5.5V VDDA VSSA SDA SCL n.c.
