LT1116CS8#TRPBF

Overview

The LT1116CS8#TRPBF is a single-channel ultra-fast ground-sensing comparator in an 8-lead plastic SO package. It features a typical propagation delay of 12ns and operates from a single 5V supply or dual ±5V supplies. The input common mode range extends to the negative supply rail, allowing signals near ground to be sensed accurately. It provides complementary CMOS/TTL outputs and includes an internal latch for data retention. Key electrical specifications include a maximum input offset voltage of 3.5mV, a typical input bias current of 20µA, and a small signal voltage gain of up to 3000 V/V.

Feature Summary

• Ground-sensing capability with input common mode range extending to the negative supply rail
• Complementary outputs designed for direct interface with TTL logic
• Internal latch mechanism for retaining output data states
• Stable operation without minimum input slew rate requirements

Applications

• High speed A/D converters
• Zero crossing detectors
• Current sense for switching regulators
• Fast pulse height/width discriminators
• Line receivers

Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when ordering. Confirm the S8 package designation matches the required surface mount footprint. Ensure the temperature grade corresponds to the commercial range of 0°C to 70°C. Cross-reference the manufacturer part number with Analog Devices documentation to confirm RoHS compliance status.

Selection Notes

Select this component for applications requiring fast response times near ground potential. It serves as a pin-compatible replacement for the LT1016 in existing designs. Consider the internal latch feature if data holding capabilities are necessary. Evaluate the single-supply operation benefits for simplified power architectures compared to dual-rail solutions.

Part Context

This device belongs to the LT1116 series of high-speed comparators manufactured by Analog Devices. It shares pinout compatibility with the legacy LT1016 model. The family is characterized by ultra-fast propagation delays and precision offset specifications. It is distinct from general-purpose comparators due to its specialized ground-sensing architecture.

Replacement Considerations

LT1016 is a pin-compatible alternative within the same product family.
