• Maintains stability in unity-gain configurations while offering wide bandwidth for high-frequency signal processing.

Instrumentation, Op Amps, Buffer Amps Applications

• HDSL and ADSL line drivers
• Video distribution and buffer amplifiers
• Pulse amplification and peak detection circuits

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the manufacturer designation carefully, as National Semiconductor was acquired by Texas Instruments. Ensure the specific suffix matches the required package type and temperature grade. Confirm availability status, as older manufacturing lines may be discontinued or replaced by equivalent TI-branded components with identical electrical specifications.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when high slew rate and wide bandwidth are critical alongside moderate power consumption. It serves as a direct replacement for legacy designs using similar high-speed op-amps where voltage feedback compatibility is required. Consider the 100 mA output current for driving low-impedance loads directly.
