Overview
The MAX11900ETP+ is a 16-bit, 1Msps, single-channel, fully differential Successive Approximation Register (SAR) Analog-to-Digital Converter (ADC) produced by Analog Devices Inc./Maxim Integrated. This device is renowned for its excellent static and dynamic performance, coupled with best-in-class power consumption that scales directly with throughput. The MAX11900 features internal reference buffers, a unipolar differential ±VREF input range, and multiple supply voltages, including 3.3V for the reference buffers, 1.8V for both analog and digital supplies, and a 1.5V to 3.6V digital interface supply. It is packaged in a compact 20-pin, 4mm x 4mm TQFN package and operates over a -40°C to +85°C temperature range.
