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
