MAX11203,MAX11213數(shù)據(jù)資料

The MAX11203/MAX11213 are ultra-low-power (< 300FAactive current), high-resolution, serial-output ADCs.These devices provide the highest resolution per unitpower in the industry, and are optimized for applicationsthat require very high dynamic range with low power,such as sensors on a 4mA to 20mA industrial controlloop. Optional input buffers provide isolation of the signalinputs from the switched capacitor sampling networkallowing these converters to be used with high-impedancesources without compromising available dynamicrange or linearity. The devices provide a high-accuracyinternal oscillator that requires no external components.When used with the specified data rates, the internaldigital filter provides more than 100dB rejection of 50Hzor 60Hz line noise. The devices are configurable usingthe SPI interface and include four GPIOs that can beused for external mux control. The MAX11213 includesdigital programmable gain of 1 to 128.
