ZSSC3026 Low Power, High Resolution 16-Bit Sensor Signal Conditioner Datasheet Brief Description Benefits The ZSSC3026 is a sensor signal conditioner (SSC) Excellent for low-voltage and low-power battery integrated circuit for high-accuracy amplification and applications analog-to-digital conversion of a differential input Integrated 18-bit calibration math DSP signal. Developed for correction of resistive bridge Costs minimized via one-pass calibration sensors and optimized for high-resolution altimeter No external trimming components required module applications, the ZSSC3026 can perform st nd Highly integrated CMOS design offset, span, and 1 and 2 order temperature com- pensation of the measured signal. It can also provide a corrected temperature output measured with an Physical Characteristics internal sensor. The corrected measurement values Supply voltage range: 1.8 to 3.6V are provided at the digital output pins, which can be 2 Current consumption: 900A (operating mode) configured as I C* (3.4MHz) or SPI ( 20MHz). Sleep State current: 50nA (typical) Digital compensation of the signal offset, sensitivity, Temperature resolution: <0.003K/LSB temperature, and non-linearity is accomplished via an 18-bit internal digital signal processor (DSP) run- Operation temperatures depending on part ning a correction algorithm. Calibration coefficients number: 40C to +85C are stored on-chip in a highly reliable, non-volatile, Small die size multiple-time programmable (MTP) memory. Prog- Delivery options: die for wafer bonding, bumped ramming the ZSSC3026 is simple via the serial die for Flip Chip, PQFN24 interface. An internal charge pump provides the programming voltage. The interface is used for the PC-controlled calibration procedure, which programs Typical Applications the calibration coefficients in memory.
