Overview
The MAX11339ATJ+ is a high-performance, low-power analog-to-digital converter (ADC) produced by Maxim Integrated, now part of Analog Devices Inc. This device is part of the MAX11335–MAX11340 family, which features 12-/10-bit resolution with an external reference and a 500kHz full-linear-bandwidth conversion rate. It is designed for high-speed, low-power applications and is particularly suited for multichannel data acquisition systems.
The MAX11339ATJ+ offers a highly integrated solution with external access to the output of the integrated multiplexer and ADC input, simplifying signal conditioning. It supports both internal and external clock modes, including internal averaging to enhance signal-to-noise ratio (SNR) and SampleSet™ technology for flexible input channel sequencing.
