What are the key features of LT1394CMS8#TRPBF?
- 7 ns propagation delay enabling precision high-speed threshold detection at clock rates up to 100 MHz in pulse-width measurement and zero-crossing detection circuits
- Low 7 µA input bias current and 4 mV maximum offset voltage deliver accurate comparisons with high-impedance sensor signals without introducing significant systematic error
- 8-pin MSOP (PDSO-G8) package with ±5 V supply compatibility fits compact mixed-signal PCB layouts alongside op-amp-based signal conditioning stages
What is LT1394CMS8#TRPBF used for?
The LT1394CMS8#TRPBF is deployed in high-speed data acquisition systems, precision motor control commutation circuits, and oscilloscope trigger comparators where the 7 ns response time and low input offset voltage together ensure accurate threshold crossing detection at signal slew rates exceeding 100 V/µs. Its low bias current also makes it suitable for battery-powered portable instruments and waveform digitizers that compare sensor voltages to precision reference levels with minimal self-heating at the input nodes.

Frequently Asked Questions
How fast is the LT1394CMS8#TRPBF and what signal frequencies can it reliably detect threshold crossings at?
The LT1394 has a 7 ns propagation delay, which allows it to detect threshold crossings on signals with slew rates up to several hundred V/µs and to resolve pulse widths as narrow as 15 ns. In practice this speed supports reliable operation at input signal frequencies exceeding 50 MHz, making it suitable for clock recovery, zero-crossing detectors, and high-speed data line receivers in instrumentation applications.
What is the input offset voltage specification of LT1394CMS8#TRPBF and how does it affect precision comparator designs?
The maximum input offset voltage is 4 mV (4000 µV), which means the comparator can resolve voltage differences as small as 4 mV without systematic comparison error at 25°C. For a 10 V full-scale input range this corresponds to 0.04% accuracy, adequate for most industrial threshold detectors and over-voltage protection circuits without external trim components or calibration routines.
What supply voltage range does LT1394CMS8#TRPBF accept and which power supply configurations does that support?
The device operates from a dual supply with nominal ±5 V (negative supply limit of -7 V maximum) and can also run from a single 5 V supply with inputs biased at mid-supply. The ±5 V dual-supply topology is common in audio signal processing, analog front-end circuits, and mixed-signal measurement boards where bipolar signal swings must be compared against a ground-referenced threshold without clipping.
For a compact portable instrument, how does the 8-pin MSOP package of LT1394CMS8#TRPBF compare to a DIP alternative in board area?
The MSOP-8 (PDSO-G8) package occupies approximately 14.7 mm² of PCB footprint compared to roughly 100 mm² for an 8-pin DIP, a reduction of approximately 85% in board area. This size reduction allows multiple comparator channels to be placed on a single small-form-factor PCB alongside analog filtering and ADC stages, which is critical for handheld test instruments and wearable medical monitors with board dimensions under 30 mm × 30 mm.
