Overview
The MAX11161EUB+T is a 16-bit, 250ksps Successive Approximation Register (SAR) Analog-to-Digital Converter (ADC) produced by Analog Devices Inc./Maxim Integrated. This ADC is designed to offer excellent AC and DC performance with a true unipolar input range, an internal reference, and a compact size. It operates with a single 5V supply and measures an input range of 0 to 5V. The MAX11161EUB+T integrates a low drift reference with an internal buffer, eliminating the need for an external reference and thus saving cost and space.
