AD96687BR

Overview

The AD96687BR is a dual ultrafast voltage comparator from Analog Devices, housed in a 16-pin SOIC package. It operates within an industrial temperature range of -25°C to +85°C and requires dual power supplies of +5.0 V and -5.2 V. The device features a propagation delay of 3.5 ns maximum and a low dispersion of 50 ps. It includes level-sensitive latch inputs for track-hold or sample-hold modes. Outputs are complementary open-emitter types compatible with ECL logic families.

Feature Summary

• Dual-channel architecture providing two independent high-speed comparators in a single package.
• Ultrafast switching performance with minimal propagation delay dispersion for consistent timing accuracy.
• Integrated level-sensitive latch functionality enabling flexible tracking, track-hold, or sample-hold operation modes.
• High-precision differential input stage supporting a wide common-mode voltage range.

Applications

• High speed triggers
• Threshold detectors
• Window comparators
• Peak detectors

Procurement Notes

Verify the specific suffix BR indicates the 16-pin SOIC industrial grade variant when sourcing. Confirm that the application circuit provides proper ECL termination resistors connected to -2.0 V for the open-emitter outputs. Ensure power supply decoupling meets high-speed design requirements to maintain signal integrity. Check for availability as this component may have limited distribution channels.

Selection Notes

Select the AD96687BR when dual comparator functionality is required alongside ultrafast response times. This model is suitable for designs needing latch capabilities for sampling applications. Consider the 16-pin SOIC package constraints if board space is limited. Evaluate thermal dissipation requirements given the power consumption characteristics of the dual-channel configuration.

Part Context

This component belongs to the AD96685/AD96687 family of ultrafast comparators. While the AD96685 offers a single channel, the AD96687 provides dual channels with identical speed specifications. Both share the same electrical characteristics and pinout compatibility where applicable, allowing for scalable design implementations requiring multiple comparison stages.

Replacement Considerations

The AD96687BQ (DIP) and AD96687BP (PLCC) offer equivalent electrical performance with different physical packages. Direct pin-compatible substitution is possible only if the target footprint matches the 16-pin SOIC form factor. Verify mechanical clearance and thermal management requirements before selecting alternative package variants.
