ZMDI releases the versatile ZSSC3018 High-Resolution 18-Bit Sensor Signal Conditioner for high-accuracy amplification and analog-to-digital conversion of a differential or pseudo-differential input signal

ZMDI ZSSC3018

ZMD AG (ZMDI) announces the new ZSSC3018 High-Resolution 18-Bit Sensor Signal Conditioner (SSC). As a global supplier of analog and mixed-signal solutions for automotive, industrial, medical, information technology and consumer applications, ZMDI is pleased to introduce an SSC designed for high-resolution sensor module applications. The ZSSC3018 is available in a PQFN24 package.

ZMDI - ZSSC3018

The ZSSC3018 can perform offset, span, and 1st and 2nd order temperature compensation of the measured signal. Developed for correction of resistive bridge or absolute voltage sensors, it can also provide a corrected temperature output measured with an internal sensor. The ZSSC3018 has calibration coefficients that are stored on-chip in a highly reliable, non-volatile, multiple-time programmable (MTP) memory which enables simple programming via the serial interface. The ZSSC3018 provides accelerated signal processing, increased resolution, and improved noise immunity in order to support high-speed control, safety, and real-time sensing applications with highest requirements for energy efficiency.
