The MAX11202 is an ultra-low-power (< 300FA max

active current), high-resolution, serial output ADC. This

device provides the highest resolution per unit power in

the industry and is optimized for applications that require

very high dynamic range with low power such as sensors

on a 4mA to 20mA industrial control loop. The MAX11202

provides a high-accuracy internal oscillator that requires

no external components.

When used with the specified data rates, the internal digital

filter provides more than 80dB rejection of 50Hz or 60Hz

line noise. The MAX11202 provides a simple 2-wire serial

interface in the space-saving, 10-pin FMAX

The MAX11202 operates over the -40NC to +85NC tem-

perature range.
