Overview
The MAX11156ETC+T, produced by Analog Devices Inc./Maxim Integrated, is an 18-bit, 500ksps Successive Approximation Register (SAR) Analog-to-Digital Converter (ADC). This component is distinguished by its excellent AC and DC performance, true bipolar input range, and compact size. It operates from a single 5V supply and can measure a ±5V (10V peak-to-peak) input range. The MAX11156 integrates an optional internal reference and buffer, which helps in saving additional cost and space. It achieves high accuracy with 94.6dB Signal-to-Noise Ratio (SNR) and -101.4dB Total Harmonic Distortion (THD).
