LMH6609MF

Overview

The LMH6609MF is a single-channel voltage feedback operational amplifier manufactured by Texas Instruments. It features a gain-bandwidth product of 260 MHz and a slew rate of 1400 V/µs. The device operates within a supply voltage range of 6 V to 12 V, with a maximum dual supply of 6 V. Key electrical parameters include an input offset voltage of 800 µV, input bias current of 2 µA, and output current capability of 90 mA per channel. It has a -3 dB bandwidth of 900 MHz and an input noise current density of 1.6 pA/√Hz. The component is housed in a SOT-23-5 package and supports an operating temperature range from -40°C to 85°C.

Feature Summary

• High-speed voltage feedback architecture designed for demanding signal processing applications.
• Capable of delivering high output drive current to support low-impedance loads.
• Compact surface-mount packaging facilitates integration into space-constrained circuit designs.

Applications

• Video buffering and signal conditioning
• High-speed data acquisition systems
• Test and measurement instrumentation

Procurement Notes

Verify the specific suffix and RoHS compliance status before procurement, as the LMH6609MF may be obsolete or restricted. Confirm that the delivered unit matches the exact pinout and electrical specifications required for the design. Cross-reference with active alternatives like the LMH6609MF/NOPB if environmental compliance is mandatory for the target market.

Selection Notes

Select this component when a single-channel amplifier with high slew rate and moderate bandwidth is required in a small footprint. Ensure the application does not exceed the 12 V maximum supply voltage limit. Consider the input offset voltage and bias current characteristics against the precision requirements of the signal chain. Verify thermal management capabilities within the SOT-23-5 package for the expected power dissipation.

Part Context

The LMH6609MF belongs to the LMH6609 series of high-speed operational amplifiers from Texas Instruments. This series is engineered for video and broadband applications requiring fast transient response. The MF variant specifically denotes the SOT-23-5 surface-mount package configuration. It serves as a foundational component in analog signal paths where speed and compact size are prioritized over ultra-low noise performance.

Replacement Considerations

The LMH6609MF/NOPB is a direct replacement offering RoHS compliance. Other potential substitutes include the MAX4104EUK+T and MAX4304EUK+T from Analog Devices, though pinouts and electrical characteristics must be verified for compatibility.
