View Datasheet Manufacturer Site View Pricing & Stock

The AD9644 is a dual, 14-bit, analog-to-digital converter (ADC) with a high speed serial output interface and sampling speeds of either 80 MSPS or 155 MSPS.The AD9644 is designed to support communications appli-cations where high performance, combined with low cost, small size, and versatility, is desired. The JESD204A high speed serial interface reduces board routing requirements and lowers pin count requirements for the receiving device.The dual ADC core features a multistage, differential pipelined architecture with integrated output error correction logic. Each ADC features wide bandwidth differential sample-and-hold analog input amplifiers that support a variety of user-selectable input ranges. An integrated voltage reference eases design consid-erations. A duty cycle stabilizer is provided to compensate for variations in the ADC clock duty cycle, allowing the converters to maintain excellent performance.By default, the ADC output data is routed directly to the two external JESD204A serial output ports. These outputs are at CML voltage levels. Two modes are supported such that output coded data is either sent through one data link or two. (L = 1; F = 4 or L = 2; F = 2). Independent synchronization inputs (DSYNC) are provided for each channel.Flexible power-down options allow significant power savings, when desired.Programming for setup and control is accomplished using a 3-wire SPI-compatible serial interface.The AD9644 is available in a 48-lead LFCSP and is specified over the industrial temperature range of −40°C to +85°C.This product is protected by a U.S. patent.
