LMH6611MKX/NOPB

Overview

The LMH6611MKX/NOPB is a single-channel, high-speed operational amplifier manufactured by Texas Instruments. It features rail-to-rail input and output capabilities, making it suitable for low-voltage applications. The device operates on a single supply voltage ranging from 2.7 V to 5.5 V. Key electrical specifications include a gain-bandwidth product of 345 MHz, a slew rate of 1000 V/µs, and a typical input offset voltage of 2 mV. It draws a quiescent current of 3.2 mA per channel and provides an output short-circuit current capability of 100 mA. The component is housed in a compact SOT-23-6 surface-mount package.

Feature Summary

• Rail-to-rail input and output operation enables full signal swing near supply rails.
• High-speed performance with 345 MHz gain-bandwidth product supports wideband signal processing.
• Low power consumption with 3.2 mA quiescent current per channel optimizes energy efficiency.
• Robust output drive capability with 100 mA short-circuit protection ensures reliability.

Applications

• Video buffering and distribution circuits
• Portable instrumentation requiring high bandwidth
• Active filtering in communication systems
• ADC driver stages for data acquisition

Procurement Notes

Verify the complete part number including the suffix /NOPB to confirm lead-free compliance and RoHS status. Ensure the SOT-23-6 package variant matches your PCB footprint requirements. Confirm that the operating temperature range of -40°C to +125°C aligns with your system's environmental conditions before finalizing procurement.

Selection Notes

Select this component when rail-to-rail I/O is required alongside high bandwidth in a small form factor. It is appropriate for single-supply designs where signal integrity near ground or VCC is critical. Consider the 3.2 mA current draw against power constraints. The SOT-23-6 package limits thermal dissipation compared to larger packages, so verify thermal management needs for continuous high-current operation.

Part Context

This device belongs to the LMH6611 series of high-speed amplifiers from Texas Instruments. It is part of a family designed for video and broadband applications. The MKX/NOPB designation indicates a specific tape-and-reel packaging option with no lead content. It shares architectural similarities with other members of the LMH66xx series but offers distinct pinout and performance characteristics tailored for space-constrained designs.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing circuit designs if considering alternative high-speed op-amps, as pinouts and electrical parameters may differ significantly between manufacturers and families.
