Introduction

AI Translation

The MAX11261 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 device also features a 64-entry, on-chip FIFO to offload the host processor. The MAX11261 communicates through an I2C-compatible serial interface and is available in a small, wafer-level package (WLP). The MAX11261 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 MAX11261 to interface directly with high-impedance sources without compromising the available dynamic range. The MAX11261 operates from a single 2.7V to 3.6V analog supply. The digital supply range is 1.7V to 2.0V (internal LDO off) and 2.0V to 3.6V (internal LDO on) enabling communication with 1.8V, 2.5V, 3V, or 3.3V logic.
