LM6172IM

Instrumentation, Op Amps, Buffer Amps Overview

The LM6172IM is a dual high-speed voltage feedback operational amplifier manufactured by Texas Instruments. It features a gain-bandwidth product of 100 MHz and a slew rate of 3000 V/µs. The device operates on supply voltages ranging from 5.5 V to 36 V, with a maximum operating temperature of 85°C. Each channel draws 2.3 mA of supply current while delivering up to 90 mA of output current. Input offset voltage is specified at 400 µV, and input bias current is 1.2 µA. The component is housed in an 8-SOIC package.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix and revision level when sourcing replacements, as the original LM6172IM may be discontinued. Confirm RoHS compliance status and check for equivalent NOPB versions that maintain identical electrical specifications. Ensure the replacement part matches the 8-SOIC footprint and thermal characteristics required for the target application design.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component for applications requiring fast transient response and low distortion without excessive power draw. The dual-channel configuration simplifies board space compared to single op-amps. Consider the 36 V maximum supply limit and 85°C junction temperature rating during system design. Verify that the 100 MHz bandwidth meets the signal frequency requirements for the intended circuit topology.

Instrumentation, Op Amps, Buffer Amps Part Context

The LM6172IM belongs to the LM617x family of high-speed amplifiers from Texas Instruments. This series utilizes a complementary bipolar process to achieve performance metrics suitable for broadband signal processing. The dual-channel variant provides matched characteristics between channels, which is critical for differential signaling applications. It serves as a successor to earlier National Semiconductor designs now managed under TI's portfolio.
