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.
