Overview
The MAX11165ETC+ is a 16-bit, 250ksps Successive Approximation Register (SAR) Analog-to-Digital Converter (ADC) produced by Analog Devices Inc./Maxim Integrated. This ADC is designed to offer excellent AC and DC performance, featuring a unipolar input range and an optional internal reference and buffer. This integration helps in saving additional cost and space in the system. The MAX11165ETC+ is known for its high accuracy, achieving 92.4dB Signal-to-Noise Ratio (SNR) and -104.2dB Total Harmonic Distortion (THD), along with 16-bit no-missing codes and ±0.6 LSB Integral Non-Linearity (INL) typical. It communicates via an SPI-compatible serial interface, supporting various logic levels and enabling daisy-chaining for multichannel applications.
