EVALUATION KIT AVAILABLE

MAX11254

24-Bit, 6-Channel, 64ksps, 6.2nV/√Hz PGA,

Delta-Sigma ADC with SPI Interface

General Description

Beneﬁts and Features

● High Resolution for Industrial Applications that

The MAX11254 is a 6-channel, 24-bit delta-sigma ADC

that achieves exceptional performance while consuming

very low power. Sample rates up to 64ksps allow preci-

sion DC measurements. The MAX11254 communicates

via a SPI serial interface and is available in a small (5mm

x 5mm) TQFN package.

Require a Wide Dynamic Range

• 133dB SNR at 50sps

• 124dB SNR at 1000sps

● Longer Battery Life for Portable Applications

• 2.2mA Operating Mode Current

• 1μA Sleep Current

The MAX11254 offers a 6.2nV/√Hz noise programmable

gain amplifier (PGA) with gain settings from 1x to 128x.

The integrated PGA provides isolation of the signal inputs

from the switched capacitor sampling network. The PGA

also enables the MAX11254 to interface directly with

high-impedance sources without compromising available

dynamic range.

● Single or Split Analog Supplies Provide Input Voltage

Range Flexibility

• 2.7V to 3.6V (Single Supply) or ±1.8V (Split Supply)

● Enables System Integration

• Low Noise, 6.2nV/√Hz PGA with Gains of 1, 2, 4,

8, 16, 32, 64, 128

The MAX11254 operates from a single 2.7V to 3.6V

analog supply, or split ±1.8V analog supplies, allowing

the analog input to be sampled below ground. The digital

supply range is 1.7V to 2.0V or 2.0V to 3.6V, allowing

communication with 1.8V, 2.5V, 3V, or 3.3V logic.

• 6-Channel, Fully Differential Input

● Enables On-Demand Device and System Gain and

Offset Calibration

• User-Programmable Offset and Gain Registers

Applications

● Analog I/O for Programmable Logic Controllers

● Weigh Scales

● Pressure Sensors

● Robust Performance in a Small Package

• -40°C to +125°C Operating Temperature Range

• TQFN Package, 5mm x 5mm

● Battery-Powered Instrumentation
