Maxim MAX11259AWX+T

Overview

The MAX11259AWX+T 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 MAX11259AWX+T communicates via an I2C-compatible serial interface and is available in a small (3mm x 3mm) WLP package. The MAX11259AWX+T 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 MAX11259AWX+T to interface directly with high-impedance sources without compromising available dynamic range. The MAX11259AWX+T 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.
