The front end is configurable via the SPI, making the device ideal for pressure and temperature sensors, flowmeters, thermostats, digital panel meters, and PLCs.
The internal 16-bit ΔΣ A/D converter can sample at rates from 0.814ksps to 6.51ksps and has a single-ended, differential and pseudo-differential input. NJU9103 is available in package sizes of 2.3 x 2.3 mm (DFN8) or 3.5 x 6.4mm (SSOP8).
The NJU09103 can be combined with the STM32F429 MCU for cost-effective sensor signal processing. Signal analysis and synthesis are easy to implement with the respective evaluation boards of the front end and the microcontroller along with a few passive components. The sinus signal can be visualised with the aid of a connected display. It operates similar to an oscilloscope but can output additional information on the slew rate, resolution, and accuracy of NJU9103.
