- 7ns at 5mV Overdrive
- Low Power: 4.2mA at 3V
- Separate Input and Output Power Supplies (SO-8 Only)
- Output Optimized for 3V and 5V Supplies
- TTL/CMOS Compatible Rail-to-Rail Output
- Low Power Shutdown Mode: 0.1μA
- Low Profile (1mm) SOT-23 (ThinSOT™) Package
The LT1719 is an UltraFast™ comparator optimized for low voltage operation. The input voltage range extends from 100mV below VEE to 1.2V below VCC. Internal hysteresis makes the LT1719 easy to use even with slow moving input signals. The rail-to-rail outputs directly interface to TTL and CMOS. Alternatively the symmetric output drive can be harnessed for analog applications or for easy translation to other single supply logic levels. A shutdown control allows for reduced power consumption and extended battery life in portable applications.
The LT1719 is available in the SO-8 and 6-lead SOT-23 package. The SO-8 package has separate supplies which allow flexible operation, accomodating separate analog input ranges and output logic levels.
For a dual/quad comparator with similar performance, see the LT1720/LT1721.
