Overview
The LT685CN#PBF is an ultrafast comparator from Analog Devices, featuring differential inputs and complementary outputs fully compatible with ECL logic levels. It operates on a supply voltage ranging from 3V to 3.6V for the related LTC1385 series context, but specifically for the LT685, the maximum supply voltage is 18V. The device exhibits a typical CMRR of 80dB and a maximum propagation delay of 6.5ns. It is housed in a 16-DIP package with through-hole mounting and functions within an operating temperature range of -30°C to 85°C.
Feature Summary
- Ultrafast comparison speed with differential inputs
- Complementary outputs compatible with ECL logic levels
- High common-mode rejection ratio
Applications
- High-speed signal processing circuits
- ECL logic interface applications
- Precision timing circuits requiring fast response
Procurement Notes
Verify component authenticity by checking manufacturer markings and datasheet specifications against official Analog Devices documentation. Confirm package type and pinout compatibility with existing designs. Ensure operating conditions match the specified voltage and temperature ranges. Review lifecycle status as components may be obsolete or restricted in certain regions.
Selection Notes
Select this component when high-speed comparison is required with ECL compatibility. Consider the 16-DIP package for through-hole assembly needs. Evaluate the 6.5ns propagation delay against system timing requirements. Ensure the 18V maximum supply voltage aligns with power supply constraints. Check availability status as the component may have limited stock or obsolescence risks.
Part Context
The LT685 series represents Analog Devices' ultrafast comparator lineup designed for high-performance applications. The CN#PBF suffix indicates a specific package and lead-free variant within this family. These comparators are engineered for precision and speed, making them suitable for demanding electronic systems requiring rapid signal discrimination.
