MAX11212

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

Sigma ADC with 2-Wire Serial Interface

General Description

Features

S 18-Bit Full-Scale Resolution

S 720nV Noise (MAX11212B)

The MAX11212 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

MAX11212 provides a high-accuracy internal oscillator

that requires no external components.

RMS

S 3ppm INL

S No Missing Codes

S Ultra-Low-Power Dissipation

Operating-Mode Current Drain < 300µA (max)

Sleep-Mode Current Drain < 0.1µA

S 2.7V to 3.6V Analog Supply Voltage Range

S 1.7V to 3.6V Digital and I/O Supply Voltage Range

S Fully Differential Signal Inputs

When used with the specified data rates, the internal

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

60Hz line noise. The MAX11212 provides a simple 2-wire

serial interface in the space-saving, 10-pin FMAX pack-

age. The MAX11212 operates over the -40NC to +85NC

S Fully Differential Reference Inputs

S Internal System Clock
