Overview
The MAX11044ETN+ is a high-performance, 4-channel, 16-bit simultaneous-sampling analog-to-digital converter (ADC) produced by Analog Devices Inc./Maxim Integrated. This device is part of a family of ADCs that include the MAX11044, MAX11045, MAX11046, MAX11047, MAX11048, and MAX11049, known for their simultaneous sampling capability and high precision.
These ADCs are designed to meet the demands of various industrial and measurement applications, offering independent track and hold (T/H) and successive approximation register (SAR) circuitry for each channel. This ensures accurate and simultaneous sampling of multiple analog inputs, making them ideal for applications requiring high precision and speed.
