Sensor signal conditioner

24 July 2013 Analogue, Mixed Signal, LSI

ZMDI has launched the ZSSC3036, a 16-bit sensor signal conditioning IC with an integrated 18-bit digital signal processor (DSP) for linearisation and calibration functions.

Optimised for high-resolution industrial, consumer and medical applications, the device combines the 18-bit DSP, high-accuracy amplification, and 16-bit precision analog-to-digital conversion with special features for battery-driven low-power devices, including 900 μA typical overall current consumption, ultra-low 50 nA typical sleep mode current, and a 1,8 to 3,6 V power supply range.

It features an intelligent power saving scheme to minimise overall current consumption and an internal sensor supply regulator with an excellent power supply rejection ratio (PSRR), eliminating the need for an external buffer capacitor. This makes it attractive for applications in harsh environments.

Digital compensation of signal offset, sensitivity, temperature and non-linearity is accomplished via an internal correction algorithm with coefficients stored on-chip in a highly reliable, non-volatile, multiple-time programmable memory. Programming is simple via the ZSSC3036’s serial interface with the PC-controlled calibration software provided in ZMDI’s development kit.

The measured and corrected bridge values are provided at the digital output pins as I²C or SPI signals. The IC can also provide a corrected temperature output measured with an internal sensor.
