GX1220 is 100% compatible with ADS1220 for analog input module

Analog input module, is used for industrial field instrumentation analog signal (0-10v, 4-20mA) acquisition of products, widely used in: pressure, flow, level, temperature, concentration, valve position and other field instrumentation information acquisition. Combined with AO module, DI module, DO module and ProfiNet network module, it constitutes a distributed slave station, realizing signal acquisition and control output of instruments, meters and equipments of industrial automation system.

Recommend the use of GX1220, it is a low-power, low-noise, highly integrated complete analog front-end, internal PGA, VREF, SPI and two IDAC 24-bit 3.7kSPS six-channel low-power Δ-sigma ADC. and the analog-to-digital converter can be compatible with the ADS1220 hardware & software, GX1220 in the price of a certain advantage under the premise of GX1220 has the same excellent performance with the price advantage, if you need, you can apply for the sample.
