General Description
The MAX11200/MAX11210 are ultra-low-power (< 300FA
active current), high-resolution, serial output ADCs. These
devices provide the highest resolution per unit power in
the industry, and are optimized for applications that
require very high dynamic range with low power, such as
sensors on a 4mA to 20mA industrial control loop. Optional
input buffers provide isolation of the signal inputs from the
switched capacitor sampling network allowing these converters to be used with high-impedance sources without
compromising available dynamic range or linearity. The
devices provide a high-accuracy internal oscillator that
requires no external components. When used with the
specified data rates, the internal digital filter provides
more than 100dB rejection of 50Hz or 60Hz line noise.
The devices are configurable using the SPI interface and
are available in a 16-pin QSOP package.
