1.3 MHz GBW at 20 µA — the power-conscious choice
The Analog Devices LTC6258IS6#TRMPBF is a single-supply, general-purpose op-amp that delivers a 1.3 MHz gain-bandwidth product while drawing just 20 µA of supply current. The rail-to-rail output swing lets it drive ADC inputs or low-voltage rails without a second supply.
Package and mounting
The 0.24 V/µs slew rate is typical for a micropower amplifier; it limits large-signal bandwidth to roughly 19 kHz at 2 Vpp output. For audio or low-frequency sensor signals that is plenty, but do not expect fast pulse response. Input offset voltage is 400 µV max and input bias current is 75 nA — adequate for most general-purpose work, though you would pick a CMOS-input part for high-impedance sources.
Package and rework — TSOT-23-6
Housed in a TSOT-23-6 package, this is a small six-pin part with a 0.95 mm pitch. The thin SOT-23 outline means low thermal mass — it reflows cleanly with a standard profile and lifts easily under hot air if you need to swap it. No exposed pad, so no via-stitch worry; just keep the traces short to the supply bypass cap.
