ZMDI Introduces Precision Signal Conditioner

May 16, 2012

The ZSSC3154 IC includes a dual analog output interface and supports high-performance automotive and industrial applications.


DRESDEN, Germany /PRNewswire/ -- Zentrum Mikroelektronik Dresden AG (ZMDI), a Dresden-based semiconductor company that specializes in enabling energy-efficient solutions, announces an additional member of their ZSSC product family, the ZSSC3154. As a global supplier of analog and mixed-signal solutions for automotive, industrial, medical, information technology, and consumer applications, ZMDI introduces the ZSSC3154 as a valuable addition to their portfolio of signal sensor conditioners. It is well suited to many automotive and industrial applications.

With the ZSSC3154, two different input signals, such as a pressure signal from a resistive full bridge and temperature from an external temperature sensor (diode or positive temperature coefficient resistor), are read out using one IC. The ZSSC3154 also measures the temperature of the full bridge sensor either externally or directly on the chip to compensate for the sensor's offset, gain and temperature coefficient up to the second order and nonlinearity failures up to the third order. The signal from the ambient temperature sensor is also digitally compensated for offset, gain, and nonlinearity up to the second order. These digital corrections are performed by a 16-bit RISC microcontroller, using coefficients and settings stored in an onboard EEPROM memory. Different programmable configurations of the two analog outputs allow reading both measurement results simultaneously or generating two complementary (normal and antivalent) signals from the full-bridge sensor for controlling the correct sensor-to-module communication over time.

"The various configurable output options of the two analog output channels allow our customers to setup applications with redundant output signals. An example of application areas for the ZSSC3154 may include automotive ABS/ESC applications" stated Frank Schulze, Business Line Manager for Sensing and Automotive at ZMDI.

The ZSSC3154 allows a digital one-pass end-of-line calibration with integrated broken-chip detection, enabling fully automatic and highly efficient mass production for noncalibrated sensing elements. The IC is available as die or in a QFN32 5 by 5 mm plastic package, compliant with the JEDEC standard. The ZSSC3154 is qualified according to AEC-Q100 automotive standards for an operational temperature range between –40°C and 125°C.

The unit price is €4,60/$6.22 for packaged parts in tubes, with a minimum order of 1000 ICs, or €1,56/$2.11 for die on frame, with a minimum order of 10,000 die. The IC is available for volume production.
