The SPT7722 is a high-speed,8-bit analog-to-digital converterimplemented 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 highrate and very lowpower dissipation of only 425mW.The analog inputs can be operated in either single-ended or differential input mode.A 2.5V common mode reference isprovided on chip for the single-ended input mode to minimize external components.

The SPT7722 digital outputs are demuxed(double-wide)withboth dual-channel and single-channel selectable output modes.Demuxed modesupports either parallel aligned orinterleaved 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 temperaturerange of -40°C to +85°C.
