The MAX11201 is an ultra-low-power (< 320FA 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 MAX11201
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 100dB rejection of 50Hz or 60Hz
line noise. The MAX11201 provides a simple 2-wire serial
interface in the space-saving, 10-pin FMAX
The MAX11201 operates over the -40NC to +85NC tem-
perature range.
Note: All devices are specified over the -40°C to +85°C oper-
ating temperature range.
+Denotes a lead(Pb)-free/RoHS-compliant package.
