LT1711IMS8#PBF

Overview

The LT1711IMS8#PBF is a single UltraFast comparator featuring rail-to-rail inputs and complementary outputs. It operates on a single supply from 2.4V to 12V or dual supplies of ±2.4V to ±6V. The device includes an internal TTL/CMOS compatible latch for data retention. Propagation delay is 4.5ns at 20mV overdrive and 5.5ns at 5mV overdrive. Input offset voltage is typically 5mV, with input bias current ranging from -3µA to 10µA. Supply current is 15mA per comparator at 5V. It is housed in an 8-lead MSOP package.

Feature Summary

• Rail-to-rail inputs extend 100mV beyond supply rails without phase reversal
• Complementary outputs interface directly to TTL or CMOS logic
• Internal latch retains output data when latch pin is held high

Applications

• High speed automatic test equipment
• Current sense for switching regulators
• Crystal oscillator circuits
• High speed sampling circuits
• Window comparators

Procurement Notes

Verify the specific suffix #PBF indicates lead-free and RoHS compliance status according to Analog Devices documentation. Confirm the IMS8 designation corresponds to the industrial temperature range (-40°C to 85°C) and the 8-lead MSOP package type. Ensure ordering matches the single-channel configuration distinct from the dual-channel LT1712 variant.

Selection Notes

Select this component for applications requiring ultrafast propagation delays near 4.5ns. It is optimized for 3V and 5V power supplies but supports wider voltage ranges. The integrated latch simplifies digital interfacing by holding output states. Consider the complementary output structure for direct logic driving without additional pull-up components.

Part Context

This part belongs to the LT1711/LT1712 family of UltraFast comparators. The LT1711 is the single-channel version packaged in MSOP, while the LT1712 is the dual-channel version in SSOP. Both share identical electrical characteristics and features, differing only in channel count and package form factor.

Replacement Considerations

LT1713CMS8#PBF offers similar functionality with lower power consumption (5mA) and slightly slower speed (7ns). LT1719 provides comparable speed with level shifting capabilities.
