Application NoteAnalog
A Seven-Nanosecond Comparator for Single Supply Operation (AN72)
Technical guidance for the LT1394 7ns comparator, focusing on single-supply operation, high-speed design techniques, and various oscillator and trigger application circuits.
Overview
This application note introduces the LT1394, a high-speed TTL comparator designed for single-supply operation with an input range that includes ground. It provides an in-depth exploration of high-speed circuit design challenges, including bypassing, probe compensation, grounding, and parasitic management. The document includes tutorials on test equipment like oscilloscopes and pulse generators, as well as practical applications such as crystal oscillators, 10MHz voltage-to-frequency converters, adaptive triggers, 10ns sample-and-hold circuits, and overvoltage protection.
Use Cases
- High-speed signal triggering and conditioning in single-supply systems
- Precision voltage-to-frequency conversion up to 10MHz
- Implementation of temperature-compensated and voltage-controlled crystal oscillators
- Fast overvoltage protection with 20ns response times
- Sub-nanosecond delayed pulse generation and clock skew management
