- Features best-in-class performance and 24 bits analogue-to-digital conversion (ADC) resolution
- Enables design of sensor interfaces by providing programmable and accurate functions
Renesas Electronics Corporation has introduced the newest member of its leading-edge SSC portfolio, the ZSSC3240 sensor signal conditioner (SSC). It delivers high accuracy, sensitivity and flexibility for sensor applications such as resistive pressure sensors and medical infrared thermometers. This new SSC features best-in-class performance and speed with up to 24 bits analogue-to-digital conversion (ADC) resolution.
With 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 for developing sensing platforms from a single SSC device. This combination along with its small size makes the ZSSC3240 ideal for use with a wide variety of sensor-based devices. Applications include industrial (pressure transmitters, HVAC sensors, weight scales, factory automation devices and smart meters) consumer and medical (continuous smart health monitors).
Ease of sensor design
Micro-machined and silicon-based sensing elements mostly provide non-linear and very small signals. Therefore, it requires 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. High performance of flexible sensor front end configuration and analogue output options enable easy sensor platform design using a single IC. This allows customers to leverage the SSC cost-effectively for a wide variety of sensor elements that have different characteristics.
Key Features of the ZSSC3240 SSC
- High-gain analogue front end supporting up to 540 volt per volt (V/V)
- Integrated 26-bit DSP for high-precision sensor calibration
- 4-20 milliamps (mA) current loop output, analogue voltage outputs, and digital interfaces as I2C, SPI and OWI
- On-chip diagnostics for medical and safety applications
“With the ZSSC3240 SSC, we’ve combined best-in-class technology, know-how and leading-edge IP to provide a performance-leading, all-in-one solution that allows product designers to easily build complete sensing platforms based on a single device,” said Uwe Guenther, Senior Director of Sensing Solutions, Emerging Market Business Division at Renesas. “Customers can leverage the SSC’s leading performance, its small size, and especially its flexible configuration to realize the next generation of smart sensor-based devices for smart factories, smart buildings, smart energy, and smart healthcare.”
The ZSSC3240 SSC is available now in a 4mm x 4mm, 24-lead QFN package. The SSC is also available in bare die format.
