The MAX11259 is a 6-channel, 24-bit delta-sigma ADC that achieves exceptional performance while consuming very low power. Sample rates up to 16ksps allow precision DC measurements. The MAX11259 communicates via an I2C-compatible serial interface and is available in a small (3mm x 3mm) WLP package.
The MAX11259 offers a 6.2nV/
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 MAX11259 to interface directly with
high-impedance sources without compromising available
dynamic range.
The MAX11259 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.
