ZSSC3138 Sensor Signal Conditioner for Ceramic Sensor Applications Datasheet Brief Description Benefits The ZSSC3138 is a member of the ZSSC313x Family approach offers the best fitting IC selec- product family of CMOS integrated circuits designed tion to build cost-optimized applications for automotive/ industrial sensor applications. All No external trimming components required family members are well suited for highly accurate Low number of external components needed amplification and sensor-specific correction of PC-controlled configuration and one-pass/ resistive bridge sensor signals. An internal 16-bit end-of-line calibration via IC* or ZACwire RISC microcontroller running a correction algorithm interface: simple, cost efficient, quick, and precise compensates sensor offset, sensitivity, temperature High accuracy (0.25% FSO** -25 to +85C drift, and non-linearity of the connected sensor 0.5% FSO -40 to +125C) element. The required calibration coefficients are Optimized for automotive/industrial environments stored by the one-pass calibration procedure on chip due to robust protection circuitries, excellent (EEPROM). electromagnetic compatibility and AEC-Q100 The ZSSC3138 offers a maximum analog gain of qualification 420 and two offset compensation features. These fit perfectly with the requirements of ceramic thick-film- based sensor elements as well as strain gauges. Available Support The high amplification in combination with the offset Evaluation Kits compensation offers the capability to set up ceramic Application Notes thick-film-based sensor applications without laser Mass Calibration System trimming, which leads to better long-term stability. Physical Characteristics Features Supply voltage 4.5 to 5.5 V Adjustable to nearly all resistive bridge sensor types, analog gain of 420, maximum overall gain Operation temperature: -40C to +125C of 1680 (-40C to +150C extended temperature range Enhanced sample rate: 7.8 kHz maximum depending on product version) High ADC resolution 15/16 bit Available in RoHS-compliant JEDEC-SSOP14 package or delivery as die Safety functionality sensor connection Internal temperature compensation Digital compensation of sensor offset, sensitivity, ZSSC3138 Minimum Application Requirements temperature drift, and non-linearity Output options: ratiometric analog voltage output VCC (5 - 95% maximum, 12.4 bit resolution) or TM ZACwire (digital One-Wire Interface (OWI)) Sensor Sensor biasing by voltage Module High voltage protection up to 33 V OUT Supply current: 5.5mA maximum ZSSC3138 Reverse polarity and short circuit protection Wide operation temperature range between -40 to +150C Traceability by user-defined EEPROM entries GND 2 * Note: I C is a trademark of NXP. ** FSO = Full Scale Output. 2016 Integrated Device Technology, Inc. 1 January 25, 2016 ZSSC3138 Sensor Signal Conditioner for Ceramic Sensor Applications Datasheet ZSSC3138 Application Example Out / OWI GND C2 100nF 8 VSSE VDDE 7 V SUPP C3 +4.5V to +5.5V 47nF 9 AOUT VDD 6 Sensor Bridge 10 VBN n.c. 5 11 VBR B SCL 4 SCL Serial Interface 12 3 VBP SDA SDA 13 VBR T VSSA 2 14 N.C.
