Overview
The MAX11169EUB+T is a 16-bit, 250ksps Successive Approximation Register (SAR) Analog-to-Digital Converter (ADC) produced by Analog Devices Inc./Maxim Integrated. This ADC offers excellent AC and DC performance with a true bipolar input range, an internal reference, and a compact design. It operates from a single 5V supply and can measure a ±5V (10V peak-to-peak) input range. The MAX11169EUB+T features a patented charge-pump architecture that allows direct sampling of high-impedance sources and integrates a low drift reference with an internal buffer, reducing the need for external components.
