Product Description

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.
