What are the key features of LT1720CDD#PBF?
- Dual comparator channels with CMOS rail-to-rail inputs supporting supply voltages from 2.7 V to 5.5 V for versatile mixed-signal designs
- Push-pull output compatible with both TTL and CMOS logic levels, eliminating the need for external pull-up resistors
- Ultra-compact 8-DFN (3×3 mm) package with maximum 4.5 mV input offset voltage enabling precise threshold detection in tight PCB layouts
What is LT1720CDD#PBF used for?
The LT1720CDD#PBF is used in battery-powered portable instruments, window comparator circuits, and zero-crossing detectors where two independent rail-to-rail comparison channels must operate from a single 2.7 V to 5.5 V supply. Its push-pull output directly drives microcontroller GPIO inputs at 3.3 V or 5 V logic levels without external pull-up resistors. The 3×3 mm DFN package suits space-constrained analog front-end designs in wearables, IoT sensors, and industrial signal conditioning boards.

Frequently Asked Questions
What supply voltage range and input offset voltage spec does the LT1720CDD#PBF support?
The LT1720CDD#PBF operates from a 2.7 V to 5.5 V single supply, with a maximum input offset voltage of 4.5 mV (4500 µV) and a maximum average input bias current of 6 µA. These specs make it suitable for precision threshold detection in battery-powered 3.3 V and 5 V systems.
How does the push-pull output of the LT1720CDD#PBF simplify interface to digital logic compared to open-drain comparators?
The LT1720CDD#PBF's push-pull output actively drives both high and low logic levels without requiring an external pull-up resistor to VCC, reducing component count by at least 2 resistors in dual-channel designs and ensuring fast rise times at TTL and CMOS logic thresholds of 0.8 V and 2 V respectively.
Which compact PCB designs benefit from the 8-DFN 3×3 mm package of the LT1720CDD#PBF?
Wearable health monitors, IoT edge nodes, and portable data loggers benefit from the LT1720CDD#PBF's 8-DFN (3×3 mm) footprint, which occupies just 9 mm² of board area while providing 2 independent rail-to-rail comparator channels. This is roughly 60% smaller than an equivalent SO-8 package at 4.9×6 mm.
Is LT1720CDD#PBF a suitable alternative to LM393 in low-voltage 3.3 V applications?
Yes. The LT1720CDD#PBF operates down to 2.7 V with rail-to-rail inputs and a push-pull output, whereas the LM393 requires at least 2 V but uses open-drain output that demands an external pull-up and cannot source current. For 3.3 V systems, the LT1720CDD#PBF eliminates pull-up resistors and offers a 4.5 mV offset versus the LM393's typical 5 mV, improving threshold accuracy.
