SPT7721
8-BIT, 250 MSPS ADC WITH DEMUXED OUTPUTS
TECHNICAL DATA
NOVEMBER 8, 2001
GENERAL DESCRIPTION
The SPT7721 is a high-speed, 8-bit analog-to-digital con-
verter implemented in an advanced BiCMOS process. An
advanced folding and interpolating architecture provides
both a high conversion rate and very low power dissipation
of only 310 mW. The analog inputs can be operated in
either single-ended or differential input mode. A 2.5 V com-
mon mode reference is provided on chip for the single-
ended input mode to minimize external components.
The SPT7721 digital outputs are demuxed (double-wide)
with both dual-channel and single-channel selectable out-
put modes. Demuxed mode supports either parallel
aligned or interleaved data output. The output logic is both
+3.0 V and +5.0 V compatible. The SPT7721 is available in
a 44-lead TQFP surface mount package over the industrial
temperature range of –40 to +85 °C.
