Overview
The MAX11158EUB+T is an 18-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 and an internal reference. It operates from a single 5V supply and can measure input signals within a ±5V (10V peak-to-peak) range. The device is particularly notable for its small size, packaged in a 10-pin, 3mm x 5mm μMAX package, and is specified over the -40°C to +85°C temperature range.
