Data Sheet Rev. 1.02 / May 2012 ZSSC3026 Low Power, High Resolution 16-Bit Sensor Signal Conditioner ZSSC3026 Low Power 16 Bit Sensor Signal Conditioner IC Brief Description Benefits The ZSSC3026 is a sensor signal conditioner Integrated 18-bit calibration math DSP (SSC) integrated circuit for high-accuracy ampli- Fully corrected signal at digital output fication and analog-to-digital conversion of a differ- Minimize calibration costs through the one-pass ential input signal. Designed for high resolution calibration concept altimeter module applications, the ZSSC3026 can No external trimming components required st nd perform offset, span, and 1 and 2 order Highly integrated CMOS design temperature compensation of the measured signal. Excellent for low-voltage and low-power battery Developed for correction of resistive bridge applications sensors, it can also provide a corrected temperature output measured with an internal sensor. Physical Characteristics The measured and corrected bridge values are Supply voltage range: 1.8 to 3.6V provided at the digital output pins, which can be 2 configured as I C* ( 3.4MHz) or SPI ( 20MHz). Current consumption: 1mA (operating mode) Digital compensation of signal offset, sensitivity, Sleep State current: 50nA (typical) temperature, and non-linearity is accomplished via Temperature resolution: <0.003K/LSB an 18-bit internal digital signal processor (DSP) Operation temperatures: 40C to +85C running a correction algorithm. Calibration coeffici- 40C to +110C ents are stored on-chip in a highly reliable, non- Small die size: 1.5mm volatile, multiple-time programmable (MTP) mem- Delivery options: die for wafer bonding, ory. Programming the ZSSC3026 is simple via the bumped die for Flip Chip, PQFN24 serial interface. The IC-internal charge pump provides the MTP programming voltage. The interface is used for the PC-controlled calibration Typical Applications procedure, which programs the set of calibration coefficients in memory. The digital mating is fast The ZSSC3026 is designed for operation in and precise, eliminating the overhead normally calibrated resistive (pressure) sensor modules: associated with trimming external components and Barometric altitude measurement for portable multi-pass calibration routines. navigation Altitude measurement for emergency call Features systems Flexible, programmable analog front-end Altitude measurement for car navigation design up to 16-bit scalable, charge-balancing Inside hard disk pressure measurement two-segment analog-to-digital converter (ADC) Weather forecast Fully programmable gain amplifier accepting sensors from 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 tem- perature gain and offset drift Intelligent power management unit Layout customized for die-die bonding with sensor for high-density chip-on-board assembly Fan control Typical sensor elements can achieve accuracy of less than 0.10% FSO -40 to 110C ZSSC3026 Application Example. 2 * I C is a registered trademark of NXP. 2012 ZMD AG Rev. 1.02 All rights reserved.
