Overview
The AD9608BCPZ-105 is a dual-channel, 10-bit analog-to-digital converter (ADC) produced by Analog Devices Inc. This monolithic device operates from a single 1.8 V analog power supply and features a separate digital output driver supply to accommodate 1.8 V CMOS or 1.8 V LVDS logic families. It is designed for high performance, low power consumption, and ease of use, making it suitable for a variety of applications. The ADC includes a patented sample-and-hold circuit that maintains excellent performance for input frequencies up to 200 MHz and uses a multistage differential pipeline architecture with output error correction logic to ensure 10-bit accuracy at data rates of up to 125 MSPS.
