EVALUATION KIT AVAILABLE

MAX11203/MAX11213

16-Bit, Single-Channel, Ultra-Low-Power,

Delta- Sigma ADCs with Programmable Gain

and GPIO

General Description

Beneﬁts and Features

● Minimize Power Consumption with Ultra-Low Power

Dissipation

The MAX11203/MAX11213 are ultra-low-power (< 300µA

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 linear-

ity. 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.

• Operating-Mode Current Drain < 300µA (max)

• Sleep-Mode Current Drain < 0.4µA

● Improve Measurement Quality with Excellent DC/AC

Accuracy

• 16-Bit Noise-Free Resolution and No Missing

Codes

• 570nV

Noise at 10sps, 3.6V Input

RMS

• 3ppm INL (typ), 20ppm (max)

● Lower System Cost with Integrated Functionality

• Programmable Gain (1 to 128) (MAX11213)

• Four SPI-Controlled GPIOs for External Mux Control

• Optional Input Buffers on Both Signal and

Reference Inputs

• > 100dB (min) 50Hz/60Hz Rejection

● Increase System Accuracy with Built-in Self

Calibration

Applications

Sensor Measurement (Temperature and Pressure)

Portable Instrumentation

Battery Applications

• On-Demand Offset and Gain Self-Calibration and

System Calibration

• User-Programmable Offset and Gain Registers

Weigh Scales

● Increase System Robustness and Reliability with

2kV ESD Protection
