Signal conditioner IC
The ZSSC3240 sensor signal conditioner (SSC) from Renesas Electronics delivers high accuracy, sensitivity, and flexibility for sensor applications such as resistive pressure sensors and medical infrared thermometers.

With up to 24 bits analog-to-digital conversion (ADC) resolution, a flexible sensor front end and a broad range of output interfaces, the ZSSC3240 can be used for nearly all types of resistive and absolute voltage sensor elements, enabling customers to develop complete sensing platforms from a single SSC device. Micro-machined and silicon-based sensing elements provide mostly non-linear and very small signals, requiring special technologies to convert the sensor signal into a linearized output. The ZSSC3240 SSC facilitates both the 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. The device has a high-gain analog front end supporting up to 540 volt per volt (V/V). It features an integrated 26-bit DSP for high-precision sensor calibration. The ZSSC3240 SSC is available now in a 4x4mm, 24-lead QFN package.
