Overview
The MAX11046ETN+ is an 8-channel, 16-bit, simultaneous sampling Analog-to-Digital Converter (ADC) produced by Analog Devices Inc./Maxim Integrated. This device is packaged in a 56-pin TQFN package and features independent track and hold (T/H) and Successive Approximation Register (SAR) circuitry for each channel. It supports simultaneous sampling at a rate of 250 kSPS for each channel, making it suitable for a variety of high-speed applications.
The ADC accepts a ±5V input range and includes internal ±20mA input clamps for overrange protection. It also features a 4MHz T/H input bandwidth, an internal clock, and the option for internal or external reference. The device operates with a 4.75V to 5.25V analog supply and a separate 2.7V to 5.25V digital supply, allowing for flexible interfacing with host systems without the need for level shifters.
