1 / 26 page  Sensor Signal Conditioner for Ceramic Sensor Applications ZSSC3138 Datasheet © 2016 Integrated Device Technology, Inc. 1 January 25, 2016 Brief Description The ZSSC3138 is a member of the ZSSC313x product family of CMOS integrated circuits designed for automotive/ industrial sensor applications. All family members are well suited for highly accurate amplification and sensor-specific correction of resistive bridge sensor signals. An internal 16-bit RISC microcontroller running a correction algorithm compensates sensor offset, sensitivity, temperature drift, and non-linearity of the connected sensor element. The required calibration coefficients are stored by the one-pass calibration procedure on chip (EEPROM). The ZSSC3138 offers a maximum analog gain of 420 and two offset compensation features. These fit perfectly with the requirements of ceramic thick-film- based sensor elements as well as strain gauges. The high amplification in combination with the offset compensation offers the capability to set up ceramic thick-film-based sensor applications without laser trimming, which leads to better long-term stability. Features • Adjustable to nearly all resistive bridge sensor types, analog gain of 420, maximum overall gain of 1680 • Enhanced sample rate: 7.8 kHz maximum • High ADC resolution 15/16 bit • Safety functionality sensor connection • Internal temperature compensation • Digital compensation of sensor offset, sensitivity, temperature drift, and non-linearity • Output options: ratiometric analog voltage output (5 - 95% maximum, 12.4 bit resolution) or ZACwire TM (digital One-Wire Interface (OWI)) • Sensor biasing by voltage • High voltage protection up to 33 V • Supply current: 5.5mA maximum • Reverse polarity and short circuit protection • Wide operation temperature range between -40 to +150°C • Traceability by user-defined EEPROM entries * Note: I 2C™ is a trademark of NXP. ** FSO = Full Scale Output. Benefits • Family approach offers the best fitting IC selec- tion to build cost-optimized applications • No external trimming components required • Low number of external components needed • PC-controlled configuration and one-pass/ end-of-line calibration via I²C™* or ZACwire™ interface: simple, cost efficient, quick, and precise • High accuracy (0.25% FSO** @ -25 to +85°C; 0.5% FSO @ -40 to +125°C) • Optimized for automotive/industrial environments due to robust protection circuitries, excellent electromagnetic compatibility and AEC-Q100 qualification Available Support • Evaluation Kits • Application Notes • Mass Calibration System Physical Characteristics • Supply voltage 4.5 to 5.5 V • Operation temperature: -40°C to +125°C (-40°C to +150°C extended temperature range depending on product version) • Available in RoHS-compliant JEDEC-SSOP14 package or delivery as die ZSSC3138 Minimum Application Requirements GND OUT VCC Sensor Module ZSSC3138 |
