LMH6639MFX

Instrumentation, Op Amps, Buffer Amps Overview

The LMH6639MFX is a single-channel, high-speed voltage feedback 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 within a supply voltage range of 3 V to 12 V. Key electrical specifications include a gain-bandwidth product of 90 MHz, a slew rate of 200 V/µs, and a typical input offset voltage of 1.3 mV. It draws a supply current of approximately 4.18 mA and provides an output current of 112 mA per channel. The component is housed in an 8-SOIC package and functions reliably across an operating temperature range of -40°C to +85°C.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'MFX' against the manufacturer's official datasheet to confirm the tape-and-reel packaging configuration. Ensure the part number matches the exact pinout and thermal characteristics required for your PCB layout. Cross-reference the RoHS compliance status with the latest environmental declarations provided by Texas Instruments prior to final procurement.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a single-channel op-amp with both rail-to-rail input and output is required alongside high slew rate performance. It is appropriate for designs needing to drive low-impedance loads directly without additional buffer stages. Consider the 8-SOIC package constraints for thermal management and board space availability compared to other packages in the LMH6639 family.

Instrumentation, Op Amps, Buffer Amps Part Context

The LMH6639 belongs to Texas Instruments' VIP10™ series of high-speed amplifiers. This series is engineered for video and broadband applications where signal integrity and speed are critical. The MFX variant specifically denotes the surface-mount SOIC package option, distinguishing it from other physical form factors available within the same electrical specification family.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Publicly confirmed substitute part numbers for the LMH6639MFX are not explicitly listed in the provided reference data. Verify compatibility with alternative high-speed RRIO amplifiers by comparing gain-bandwidth product, slew rate, and output current specifications against the original design requirements.
