EVALUATION KIT AVAILABLE

MAX11253

16-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

Require a Wide Dynamic Range

• 98dB SNR at 1000sps

The MAX11253 is a 6-channel, 16-bit delta-sigma ADC

that achieves exceptional performance while consuming

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

sion DC measurements. The MAX11253 communicates

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

x 5mm) TQFN package.

● Longer Battery Life for Portable Applications

• 2.2mA Operating Mode Current

• 1μA Sleep Current

The MAX11253 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 MAX11253 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

• 6-Channel, Fully Differential Input

The MAX11253 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.

● Enables On-Demand Device and System Gain and

Offset Calibration

• User-Programmable Offset and Gain Registers

● Robust Performance in a Small Package

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

• TQFN Package, 5mm x 5mm

Applications

● Analog I/O for Programmable Logic Controllers

● Weigh Scales

● Pressure Sensors

● Battery-Powered Instrumentation
