Product introduction
24 Bit ADC SKS2302
SKS2302 is a highly integrated, low-cost, high-precision interface chip specially provided for bridge sensors to collect, amplify and calibrate sensor signals. It integrates a low-noise instrumentation amplifier (PGA), a low-power 24-bit-ΔADC, a HALFBAND filter and a 12-bit DAC. Overvoltage protection can also be supported through an external JFET. It also supports I2C/SPI digital output and analog output.

Product introduction
Temperature sensor SKATS70
The SKATS70 is an ultra-small, high-precision and low-power CMOS analog temperature sensor with output enable. Replaceable temperature sensors for RTDs and high-precision NTC/PTC thermistors. The product's output enable feature allows multiple SKATS70s to use the same ADC channel, simplifying ADC calibration and reducing the cost of systems that include high-precision temperature sensors. At the same time, high linearity and low output impedance are compatible for different MCUs or ADCs. Due to power consumption as low as 38µW or less, ultra-low temperature rises support high-precision and wide-range temperature measurements.
