“Energy-efficiency is what we do best. We designed the ZSSC3016 to provide our customers with the required resolution and accuracy for their next generation battery products,” said Michael Georgi, Engineering Manager at ZMDI. “Unlike many available products today, the ZSSC3016 comes with an internal signal correction and allows customers to minimize engineering efforts and costs.”
With a practically noise free 16-bit output signal, the ZSSC3016 allows an altitude resolution of less than 15cm at sea level. It is accurate enough for barometric altitude measurement for portable navigation or emergency call systems, altitude measurement for car navigation, inside hard disk pressure measurement, and weather forecasting equipment. Modern consumer products, such as motion sensing sport equipment or multi-function watches greatly benefit from the ZSSC3016’s precision. Medical products, which require this level of precision, include medical gas control, medical infusion pumps, ambulatory non-invasive pump systems, and occlusion detection systems.
The ZSSC3016 features an internal sensor supply regulator with an excellent power supply rejection ratio (PSRR) eliminating the need of an external buffer cap and making it attractive for mobile phones or other transmitters which are creating battery voltage dumps during operation.
Technical features
The ZSSC3016 operates at a temperature range of -40°C to +85°C. Accuracy is less than ±0.10% FSO over the full temperature range. The ZSSC3016 can perform offset, span, and first and second order temperature compensation of the measured signal. Developed for correction of resistive bridge sensors, the ZSSC3016 can provide a corrected temperature output measured with an internal sensor. The measured and corrected bridge values are provided at the digital output pins, which can be configured as I2C or SPI.
Digital compensation of signal offset, sensitivity, temperature, and non-linearity is accomplished via an 18-bit internal digital signal processor running a correction algorithm. Calibration coefficients are stored on-chip in a highly reliable, nonvolatile, multiple-time programmable memory. Programming the ZSSC3016 is simple via the serial interface and the PC-controlled calibration software provided in the ZMDI Development Kit.
Typical Applications
The ZSSC3016 is designed for operation in calibrated resistive (pressure) sensor modules:
- Barometric altitude measurement for portable navigation
