MAXIM INTEGRATED PRODUCTS  MAX1416EUE+  模数转换器, 低功率, 16 bit, 500 SPS, 单, 2.7 V, 3.6 V, TSSOP

The is a 16bit, Low power, 2-channel, sigma-delta analogue to digital converter ADC in 16 pin TSSOP package. This 2-channel fully differential serial output ADC uses a sigma-delta modulator with a digital filter to achieve 16bit resolution with no missing codes. It includes a PGA, an on-chip input buffer, an internal oscillator and a bidirectional communication port. The fully differential inputs, an internal input buffer and an on-chip PGA gain = 1 to 128 allow low level signals to be directly measured, minimizing the requirements for external signal conditioning. A programmable digital filter allows for the selection of the output data rate and first notch frequency from 20Hz to 500Hz. This device is used in weigh scales, loop-powered systems, flow and gas meters, thermocouple measurements, RTD measurements and pressure transducers.
