Overview
The MAX19517ETM+T, produced by Analog Devices Inc./Maxim Integrated, is a dual-channel, 10-bit analog-to-digital converter (ADC) with a maximum sample rate of 130Msps. This device is designed to provide excellent dynamic performance across a wide range of frequencies, making it ideal for various high-frequency applications such as zero-intermediate frequency (ZIF) and high-intermediate frequency (IF) sampling. The MAX19517 operates on a low power consumption of 74mW per channel at 1.8V supply and features an integrated self-sensing voltage regulator, allowing operation from a 2.5V to 3.3V supply (AVDD). The digital output drivers operate on an independent supply voltage (OVDD) ranging from 1.8V to 3.5V.
