SPT7722

www.fairchildsemi.com SPT7722 8-bit, 250 MSPS A/D Converter with Demuxed Outputs Features TTL/CMOS/PECL input logic compatible High conversion rate: 250 MSPS Single +5V power supply Very low power dissipation: 425mW 350 MHz full power bandwidth Power-down mode: 24mW +3.0V/+5.0V (LVCMOS) digital output logic compatibility Single/demuxed output ports selectable Improved replacement for AD9054 Description The SPT7722 is a high-speed, 8-bit analog-to-digital converter implemented in an advanced BiCMOS process. It is a performance-enhanced version of the SPT7721, offering better linearity and dynamic performance. An advanced folding and interpolating architecture provides both a high conversion rate and very low power dissipation of only 425mW. The analog inputs can be operated in either single-ended or differential input mode. A 2.5V common mode reference is provided on chip for the single-ended input mode to minimize external components. The SPT7722 digital outputs are demuxed (double-wide) with both dual-channel and single-channel selectable output modes. Demuxed mode supports either parallel aligned or interleaved data output. The output logic is both +3.0V and +5.0V compatible. The SPT7722 is available in a 44-lead TQFP surface mount package over the industrial temperature range of -40°C to +85°C.
