The SPT7721 is a high-speed, 8-bit analog-to-digital con-verter implemented in an advanced BiCMOS process. Anadvanced folding and interpolating architecture providesboth a high conversion rate and very low power dissipationof only 310 mW. The analog inputs can be operated ineither single-ended or differential input mode. A 2.5 V com-mon mode reference is provided on chip for the singleended 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 parallelaligned or interleaved data output. The output logic is both+3.0 V and +5.0 V compatible. The SPT7721 is available ina 44-lead TQFP surface mount package over the industrialtemperature range of 40 to +85 °C.
