What are the key features of LT1394CS8#PBF?
- Ultra-fast 7 ns propagation delay enabling high-speed threshold detection in ADC overdrive recovery and pulse-width discrimination circuits
- Low 7 µA maximum input bias current and 4 mV maximum offset voltage for accurate level sensing without external trim
- Single comparator in compact 8-pin SOIC package operating from ±5 V dual supplies suited to mixed-signal analog front-ends
What is LT1394CS8#PBF used for?
The LT1394CS8#PBF is used in high-speed signal detection applications such as zero-crossing detectors, ADC input protection, and line-receiver threshold circuits where 7 ns response time is critical. Its low 7 µA input bias current makes it suitable for high-impedance sensor interfaces and precision window comparators. Typical systems include industrial automation fault detectors, communications line monitors, and high-frequency pulse discriminators.

Frequently Asked Questions
How fast is the LT1394CS8#PBF propagation delay and what circuits benefit from it?
The LT1394CS8#PBF has a 7 ns propagation delay, making it one of the fastest single comparators in an 8-pin SOIC package. This speed benefits ADC overdrive recovery circuits, high-frequency zero-crossing detectors, and pulse-width discriminators operating above 10 MHz where slower comparators would introduce timing errors.
What supply voltage does LT1394CS8#PBF require and is it compatible with single-supply systems?
The LT1394CS8#PBF is designed for dual supply operation with a nominal negative supply of -5 V and a negative supply limit of up to -7 V. It is optimized for split ±5 V rails common in mixed-signal analog systems and is not intended for single-supply 3.3 V or 5 V operation without level-shifting.
What is the input offset voltage of LT1394CS8#PBF and how does it affect threshold accuracy?
The LT1394CS8#PBF has a maximum input offset voltage of 4 mV (4000 µV). This means the comparator's trip point can deviate by up to 4 mV from the set reference voltage, which is acceptable for most high-speed detection tasks but should be budgeted in precision window comparators requiring better than 5 mV threshold accuracy.
What package does LT1394CS8#PBF use and how does it fit into a high-density analog PCB?
The LT1394CS8#PBF is housed in an 8-pin SOIC package (Microchip/Linear code 05-08-1610 S8) with a 1.27 mm lead pitch and standard 3.9 mm body width. This size fits easily on a 2-layer board alongside op-amps and passive filters, and the SOIC footprint is compatible with standard pick-and-place assembly for high-volume production.
