Analog Devices Inc. AD9629BCPZRL7-80

Description
The AD9629 is a 12-bit, 20 MSPS/40 MSPS/65 MSPS/80 MSPS 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 to 3.3 V logic families. The patented sample-and-hold circuit maintains excellent performance for input frequencies up to 200 MHz and is designed for low cost, low power, and ease of use. A standard serial port interface (SPI) supports various product features and functions, such as data output formatting, internal clock divider, power-down, DCO and data output (D11 to D0) timing and offset adjustments, and voltage reference modes. The AD9629 is packaged in a 32-lead RoHS compliant LFCSP that is pin compatible with the AD9609 10-bit ADC and the AD9649 14-bit ADC, enabling a simple migration path between 10-bit and 14-bit converters sampling from 20 MSPS to 80 MSPS.
