Integrated Device Technology, Inc. introduced an energy-efficient 24-bit sensor signal conditioner (SSC) IC designed for consumer barometric pressure and thermopile sensors. With an integrated 26-bit digital signal processor (DSP) for linearization and calibration functions, the ZSSC3224 is optimized for high-resolution consumer, industrial, white goods and medical applications, and can also benefit mobile products such as phones and tablets. Developed at recently acquired Zentrum Mikroelektronik Dresden AG (ZMDI®), the ZSSC3224 expands a family of SSCs for high-end sensor modules.

Offering both accuracy and high resolution, the new sensor interface delivers high-accuracy amplification and a 24-bit precision full-featured analog-to-digital converter. With a 24-bit output signal, the ZSSC3224 is ideal for high-precision measurement systems, including barometric altitude measurement for portable navigation or emergency call systems; altitude measurement for car navigation; pressure measurements inside hard disks; and weather forecasting equipment. The device 'available in die and wafer form 'can also adapt thermopile sensors to enable contactless temperature measurements of objects or human body temperature.

Additional features of the ZSSC3224 include: Quadratic form factor, optimized for stacked die assembly. Operating temperature range:-40°C to 85°C. Easy programming via software provided in evaluation kit. Accuracy better than +0.10% full-scale output.

Internal temperature measurement and signal processing. Fully corrected digital output signal simplifying the system design.
