Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the component matches the exact part number LT1722IS5#TRMPBF, ensuring the IS5 suffix corresponds to the industrial temperature range (-40°C to 85°C) and the SOT-23-5 package. Confirm the #TRMPBF suffix indicates tape and reel packaging. Cross-reference the manufacturer's datasheet for lead-free finish specifications and RoHS compliance status before finalizing procurement orders.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this amplifier when high speed and low noise are required simultaneously. It is suitable for applications requiring high open-loop gain at video frequencies. Consider the 3.7mA supply current per amplifier against power constraints. Ensure the source resistance remains between 0.8kΩ and 12kΩ for optimal noise performance. Verify that the required output drive current does not exceed the specified limits for the chosen load conditions.

Instrumentation, Op Amps, Buffer Amps Part Context

This component belongs to the LT1722/LT1723/LT1724 family of precision op amps. The LT1722 variant specifically denotes the single-channel configuration. It is manufactured using Linear Technology’s advanced low voltage complementary bipolar process. The IS5 designation specifies the industrial temperature grade and the thin SOT-23 (TSOT-23) package format, distinguishing it from the commercial grade or other package options available in the series.
