Analog Devices Inc. AD9608BCPZRL7-105

Description
The AD9608 is a 10-bit, 125/105 MSPS, dual analog-to-digital converter (ADC) that 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 provides a patented sample-and-hold circuit that maintains excellent performance for input frequencies up to 200 MHz and is designed for low cost, low power, and ease of use. The AD9608 includes a standard serial port interface that supports various product features and functions, such as data output formatting, internal clock divider, power-down, DCO/data timing, and offset adjustments. It is packaged in a 64-lead, RoHS-compliant LFCSP that is pin compatible with the AD9650, AD9269, and AD9268 16-bit ADCs, the AD9258 and AD9648 14-bit ADCs, the AD9628 and AD9231 12-bit ADCs, and the AD9204 10-bit ADC, enabling a simple migration path between 10-bit and 16-bit converters sampling from 20 MSPS to 125 MSPS.
