Overview
The MAX11168EUB+T is a 16-bit, 500ksps Successive Approximation Register (SAR) analog-to-digital converter (ADC) produced by Analog Devices Inc./Maxim Integrated. This ADC is renowned for its excellent AC and DC performance, featuring a true bipolar input range, internal reference, and a compact design. It operates from a single 5V supply and can measure a ±5V (10V P-P) input range. The device incorporates a patented charge-pump architecture, enabling direct sampling of high-impedance sources. The MAX11168 also includes a low drift internal reference with an internal buffer, which saves on the cost and space of an external reference.
