AD9626 Series

The AD9626 is a 12-bit monolithic sampling analog-to-digital converter optimized for high performance, low power, and ease of use. The product operates at up to a 250 MSPS conversion rate and is optimized for outstanding dynamic performance in wideband carrier and broadband systems. All necessary functions, including a track-and-hold (T/H) and voltage reference, are included on the chip to provide a complete signal conversion solution.The ADC requires a 1.8 V analog voltage supply and a differential clock for full performance operation. The digital outputs are CMOS compatible and support either twos complement, offset binary format, or Gray code. A data clock output is available for proper output data timing.Fabricated on an advanced CMOS process, the AD9626 is available in a 56-lead LFCSP, specified over the industrial temperature range (−40°C to +85°C).PRODUCT HIGHLIGHTSHigh Performance–Maintains 64.9 dBFS SNR @ 250 MSPS with a 70 MHz input.Low Power–Consumes only 364 mW @ 250 MSPS.Ease of Use–CMOS output data and output clock signal allow interface to current FPGA technology. The on-chip reference and sample-and-hold provide flexibility in system design. Use of a single 1.8 V supply simplifies system power supply design.Serial Port Control–Standard serial port interface supports various product functions, such as data formatting, clock duty cycle stabilizer, power-down, gain adjust, and output test pattern generation.Pin-Compatible Family–10-bit pin-compatible family offered as the AD9601.APPLICATIONSWireless and wired broadband communicationsCable reverse pathCommunications test equipmentRadar and satellite subsystemsPower amplifier linearization
