What are the key features of LT1720CMS8#TRPBF?
- Dual comparator with 4.5 ns propagation delay enabling high-speed threshold detection at clock rates above 100 MHz
- Push-pull CMOS output compatible with 3 V and 5 V logic for direct interfacing without pull-up resistors
- 6 µA input bias current and 4.5 mV offset voltage maintaining accuracy in moderate-impedance signal conditioning circuits
- MSOP-8 small-outline package reducing board footprint by 50% versus standard SOIC-8 in space-constrained designs
What is LT1720CMS8#TRPBF used for?
The LT1720CMS8 is used in high-speed line receivers, zero-crossing detectors, and clock generation circuits where 4.5 ns propagation delay and dual comparator channels enable precise timing decisions at signal rates above 50 MHz. Its push-pull output drives logic gates and flip-flops directly without open-drain pull-up resistors, simplifying design of peak detectors, window comparators, and ADC clock conditioning networks. It also suits disk drive read channel electronics and optical receiver front-ends requiring fast signal qualification on 3.3 V or 5 V supply rails.

Frequently Asked Questions
What is the propagation delay of the LT1720CMS8, and how does it affect high-speed circuit design?
The LT1720CMS8 has a propagation delay of 4.5 ns, allowing it to resolve threshold crossings and generate valid logic outputs at signal rates exceeding 100 MHz. In a zero-crossing detector or clock recovery circuit, this delay budget leaves sufficient margin for downstream flip-flop setup times at 50 MHz to 200 MHz system clock rates, unlike general-purpose comparators with delays above 50 ns.
Does the LT1720CMS8 require external pull-up resistors for its outputs?
No. The LT1720CMS8 uses push-pull CMOS output drivers that actively source and sink current to both supply rails (3 V or 5 V). This eliminates the external pull-up resistors required by open-drain or open-collector comparators, reducing BOM by 2 resistors per channel and improving output rise times to below 2 ns on capacitive loads up to 10 pF.
For a window comparator design, how does using both channels of the LT1720CMS8 reduce component count?
A window comparator requires 2 threshold comparators whose outputs are combined to flag when a signal is within an upper and lower voltage bound. Using both channels of the single LT1720CMS8 integrates both comparators into one 8-pin MSOP package, saving 1 IC, 4 passive components, and approximately 20 mm² of board space compared to using 2 separate single-channel comparator ICs in SOT-23 packages.
How does the LT1720CMS8 input bias current of 6 µA affect source impedance selection?
At 6 µA input bias current, a source impedance of 1 kΩ introduces a 6 mV additional offset voltage error at the comparator input, which exceeds the 4.5 mV maximum offset spec and doubles the worst-case threshold error. Designers should keep source impedance below 500 Ω, or use a buffer stage if the source exceeds this limit to maintain threshold accuracy within ±10 mV across the full operating temperature range.
