Description
SROIC2100 is a generic signal conditioning circuit for reading out sensors such as RTD, thermocouples, strain gauges, etc. The SROIC2100 device provides an interface for resistive bridge sensor elements, such as RTD, thermocouple, piezo resistive, and strain-gauge pressure-sense elements. The device is a full system-on-chip (SoC) solution that incorporates a programmable gain amplifier, ADC, and digital signal processing. SROIC2100 also includes integrated voltage regulators, an on-chip temperature sensor, digital signal processing, an SPI interface, and an oscillator, thus minimizing the number of external components.
