24-Bit, Single-Channel, Ultra-Low-Power,
Delta-Sigma ADCs with GPIO
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 sig-
nal inputs from the switched capacitor sampling network
allowing these converters to be used with high-imped-
ance 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 include four GPIOs that can be
used for external mux control. The MAX11210 includes
digital programmable gain of 1, 2, 4, 8, or 16.
The MAX11200/MAX11210 operate over the -40NC to
+85NC temperature range, and are available in a 16-pin
QSOP package.
