Applications
The LT1720IMS8#3ZZPBF is designed for high-speed signal detection applications such as peak detectors, window comparators, and pulse-width measurement circuits where 7 ns response time is critical for capturing fast transients. Its rail-to-rail output directly drives 3.3 V or 5 V CMOS logic without pull-up resistors, making it ideal for level conversion, zero-crossing detection, and clock generation in mixed-signal data acquisition systems. Communications equipment, test instrumentation, and motor current sensing front-ends also use this dual comparator for simultaneous monitoring of two independent thresholds with minimal latency.

Frequently Asked Questions
How fast is the LT1720IMS8#3ZZPBF, and what signal edge rates can it reliably detect?
The LT1720IMS8#3ZZPBF achieves a propagation delay of only 7 ns, enabling detection of signal edges with rise times well below 50 ns; this makes it suitable for capturing fast transients in pulse-width modulation feedback, high-speed data strobing, and precision time-interval measurement circuits operating at tens of megahertz.
What output voltage swing does the LT1720IMS8#3ZZPBF produce, and can it drive 3.3 V CMOS inputs directly?
The LT1720IMS8#3ZZPBF features rail-to-rail outputs that swing within millivolts of both supply rails; on a 3.3 V supply the output swings from approximately 0 V to 3.3 V, providing full-swing CMOS-compatible drive for 3.3 V logic inputs without any pull-up resistor or level-shifting circuit.
What supply voltage range does the LT1720IMS8#3ZZPBF support, and does it work from a 2-cell alkaline battery?
The LT1720IMS8#3ZZPBF operates from 2.7 V to 6 V total supply, which spans two alkaline AA cells in series (nominally 3 V), a single-cell lithium-ion battery at 3.7 V, the standard 3.3 V logic rail, and the 5 V USB rail, giving designers flexibility across portable and bench-powered system architectures.
How does the dual-channel configuration of the LT1720IMS8#3ZZPBF simplify window comparator designs?
A window comparator requires two threshold comparisons simultaneously — one for the upper limit and one for the lower limit; the LT1720IMS8#3ZZPBF integrates both comparators with matched 7 ns delay in a single MSOP-8 package, ensuring both edges respond in under 10 ns and reducing component count compared to using two separate single comparators.
