LT1116CS8#PBF

Overview

The LT1116CS8#PBF is a single-channel ultra-fast analog comparator manufactured by Analog Devices Inc. in an 8-lead Plastic SO package. It features a typical propagation delay of 12 ns and operates from a single 5V supply or dual ±5V supplies. The input common mode range extends to the negative supply rail, allowing ground sensing. Key electrical parameters include a maximum input offset voltage of 3.5 mV, a typical input bias current of 20 µA, and a small signal voltage gain of up to 3000 V/V. It provides complementary CMOS/TTL outputs with an internal latch capability.

Feature Summary

• Ultra-fast response time designed for high-speed applications
• Ground-sensing inputs extending to the negative supply rail
• Complementary outputs compatible with TTL logic levels
• Internal latch mechanism for data retention

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 #PBF confirms RoHS and WEEE compliance status before procurement. Confirm the S8 package designation matches the required surface mount footprint. Ensure the operating temperature range of 0°C to 70°C aligns with the system environment. Cross-reference the manufacturer part number LT1116CS8#PBF with authorized distributors to ensure authenticity.

Selection Notes

Select this component when ground-referenced input signals are required without level shifting. The complementary output structure simplifies interfacing with digital logic families. Consider the 12ns propagation delay for timing-critical paths. Verify that the input voltage does not exceed the absolute maximum ratings during transient conditions.

Part Context

This device belongs to the LT1116 series of precision comparators. It is pin-compatible with the LT1016, facilitating direct upgrades for improved speed. The family includes variants in PDIP and SO packages. It serves as a bridge between precision analog sensing and fast digital processing stages.

Replacement Considerations

LT1016 is a pin-compatible alternative with slightly slower performance. LT1394 offers faster 7ns response times with similar pinout configurations. LT1713 provides rail-to-rail input/output capabilities with comparable speed.
