Overview
The MAX11049ETN+T, produced by Analog Devices Inc./Maxim Integrated, is a high-performance, 16-bit, simultaneous-sampling analog-to-digital converter (ADC). This device is part of the MAX11047/MAX11048/MAX11049 family, which offers 4, 6, or 8 independent input channels. It is designed for applications requiring precise and simultaneous sampling of multiple analog signals.
The MAX11049ETN+T features independent track and hold (T/H) and successive approximation register (SAR) circuitry for each channel, enabling simultaneous sampling at a rate of 250 ksps per channel. The device operates with a 4.75V to 5.25V analog supply and a flexible 2.7V to 5.25V digital supply, making it versatile for various host interfaces without the need for a level shifter.
