MAX11209/MAX11211

18-Bit, Single-Channel, Ultra-Low-Power, Delta-

Sigma ADCs with Programmable Gain and GPIO

General Description

Features

S 18-Bit Noise-Free Resolution

The MAX11209/MAX11211 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 MAX11209 includes

digital programmable gain of 1 to 128.
