ZSSC3016 Low Power 16 Bit Sensor Signal Conditioner IC Brief Description Benefits The ZSSC3016 is a sensor signal conditioner (SSC) integrated circuit for high-accuracy amplification and analog-to-digital conversion of a differential input signal. Designed for high-resolution altimeter module applications, the ZSSC3016 can perform offset, st nd span, and 1 and 2 order temperature compensation of the measured signal. Developed for correction of resistive bridge sensors, it can also provide a corrected temperature output measured with an internal sensor. Features Flexible, programmable analog front-end design; up to 16-bit scalable, charge-balancing, twosegment analog-to-digital converter (ADC) Fully programmable gain amplifier for optimizing sensor signals: gain range 14 to 72 (linear factor) Internal auto-compensated temperature sensor Digital compensation of individual sensor offset; st nd 1 and 2 order digital compensation of sensor gain st nd Digital compensation of 1 and 2 order temperature gain and offset drift Intelligent power management unit Typical sensor elements can achieve accuracy of better than ±0.10% FSO @ -40 to 85 °C Support Evaluation Kit Physical Characteristics Supply voltage range: 1.8 to 3.6V Current consumption: 1mA (operating mode) Sleep State current: 70nA (25°C) Temperature resolution: <0.003K/LSB Operation temperature: –40°C to +85 °C Small die size Delivery options: die for wafer bonding ZSSC3016 Application Example VSS VDD VSS Batte ry EOC VDD Sensor Module VDD EOC VSS Sensor Bridge SEL SEL ZSSC3016 SS SS 4 VSSB 3 INN MISO MISO 2 VDDB 1 INP MOSI SDA MOSI_SDA VPP Microcontroller Signal Output / Post-processing The measured and corrected bridge values are provided at the digital output pins, which can be 2 configured as I C™* (≤ 3.4MHz) or SPI (≤ 20MHz). Digital compensation of signal offset, sensitivity, temperature, and non-linearity is accomplished via an 18-bit internal digital signal processor (DSP) running a correction algorithm. Calibration coefficients are stored on-chip in a highly reliable, nonvolatile, multiple-time programmable (MTP) memory. Programming the ZSSC3016 is simple via the serial interface and the PC-controlled calibration software provided in the ZMDI Development Kit. The interface is used for the PC-controlled calibration procedure, which programs the set of calibration coefficients in memory. The digital mating is fast and precise, eliminating the overhead normally associated with trimming external components and multi-pass calibration routines. Integrated 18-bit calibration math DSP Fully corrected signal at digital output Minimize calibration costs through the one-pass calibration concept No external trimming components required Highly integrated CMOS design Layout customized for die-die bonding with sensor for high-density chip-on-board assembly Excellent for low-voltage and low-power battery applications SCLK SCL SCLK_SCL VPP 6.75V … programming voltage for setup & calibration * I2C™ is a trademark of NXP.
