Sensor Signal Conditioners

IDT’s sensor signal conditioner ICs (SSC ICs) facilitate both design and production of sensor interfaces by providing programmable, highly accurate, wide gain and quantization functions combined with powerful, high-order digital correction and linearization algorithms. IDT sensor signal conditioner ICs are all-in-one, energy-efficient products that are easy to use and are supported by advanced software and expert technical support staff with extensive sensor system design experience.

The "Single-pass" Calibration Advantage

Designing sensor interfaces can be quite challenging and time consuming, and producing them in volume is often expensive due to long test cycles on costly production test equipment. A distinct advantage of our correction algorithms is that they are calibrated and programmed in an efficient "single-pass" operation that lowers costs by reducing test time and loading of production test equipment without sacrificing precision. IDT sensor signal conditioner ICs also lower total system costs by simplifying sensor design with our excellent support tools, reducing external components, minimizing board space, and providing a faster migration to production.

Energy-Efficient Mixed Signal Solutions

Innovation-driven and customer-focused, we enable IC solutions that reduce fuel consumption and CO2 emissions to help protect the environment. Our products range from very low-power SSCs for mobile applications to rugged AEC-Q100-qualified ICs that expedite automotive product design by providing advanced sensor-signal conditioning and configurability while minimizing power consumption. Our sophisticated calibration and configuration techniques significantly reduce external component count and time-to-market for products that meet new emission-reduction standards.

About Sensor Signal Conditioners

Most analog signals require some form of preparation before they can be digitized. Sensor signal conditioning is the manipulation of a sensor signal in a way that prepares it for the next stage of processing. IDT’s sensor signal conditioner ICs typically interface with two main sensor types: resistive bridges and differential capacitors. For each sensor type, further specialization allows selecting the optimal balance between price and performance for the required operating voltage and temperature range, gain, resolution, input/output format, and qualification level. IDT’s SSC ICs offer digital compensation of sensor offset, sensitivity, temperature drift, and nonlinearity in wide operational temperature ranges.
