Overview
The MAX19507, produced by Analog Devices Inc./Maxim Integrated, is a dual-channel, 8-bit analog-to-digital converter (ADC) designed for high-speed and low-power applications. This ADC offers a maximum sample rate of 130Msps, making it suitable for a variety of high-frequency signal processing tasks. The device operates from a supply voltage range of 1.8V to 3.5V and features low power consumption, with only 74mW per channel at 1.8V. It also includes power-down and standby modes to further reduce power usage. The MAX19507 is packaged in a small 7mm x 7mm, 48-pin thin QFN package and is specified over an extended temperature range of -40°C to +85°C.
