LMH6628MAX

Instrumentation, Op Amps, Buffer Amps Overview

The LMH6628MAX is a dual-channel, high-speed voltage feedback operational amplifier manufactured by Texas Instruments. It features a gain-bandwidth product of 200 MHz and a slew rate of 550 V/µs. The device operates within a supply voltage range of 9 V to 6 V (likely indicating ±4.5V to ±3V or similar split/single configurations, though source text states '9 V→6V'). Key electrical parameters include an input bias current of 6 µA, input offset voltage of 2 mV, and an output current capability of 85 mA. It is housed in an 8-pin SOIC package with dimensions of 4.9 mm length and 1.45 mm height.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• High-speed performance characterized by 200 MHz gain-bandwidth product
• Fast transient response with a 550 V/µs slew rate
• Rail-to-rail input/output capability for maximum dynamic range

Instrumentation, Op Amps, Buffer Amps Applications

• Video signal processing circuits
• High-frequency data acquisition systems
• Buffer amplifiers for RF applications
• Test and measurement equipment requiring wide bandwidth

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'MAX' against the official Texas Instruments datasheet to confirm it denotes the standard commercial temperature grade (-40°C to +85°C) and SOIC-8 package variant. Ensure the ordering part number matches the exact pinout and thermal characteristics required for your PCB layout. Cross-reference the 'NOPB' designation if lead-free compliance is mandatory for your assembly process.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when dual-channel operation is required alongside high bandwidth exceeding 100 MHz. The 85 mA output current makes it suitable for driving low-impedance loads directly. Consider the 2 mV input offset voltage for precision requirements; if lower offset is needed, evaluate other family members. The SOIC-8 package offers a balance between thermal dissipation and board space efficiency compared to smaller packages.

Instrumentation, Op Amps, Buffer Amps Part Context

The LMH6628 belongs to the LMH662x series of high-speed operational amplifiers from Texas Instruments. This series is designed for applications demanding wide bandwidth and fast settling times. The dual-channel configuration allows for cost and space savings in designs requiring multiple amplification stages, such as differential drivers or active filters.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with potential replacements like the LMH6626 or LMH6629 only if their datasheets explicitly state pin-to-pin compatibility and equivalent electrical specifications.
