The 10 MHz gain-bandwidth product and 10 V/µs slew rate cover fast signal paths like ADC drivers or active filters. Supply current is 1.6 mA typical.
Rated -40°C to 125°C, so it's comfortable in an engine bay, a rooftop solar combiner box, or a factory floor panel that sees afternoon heat soak. Not just commercial-grade; this is the industrial and automotive temperature bracket.
Yes. The supply span runs from 4.5 V to 36 V, so it works on a single 5 V, 12 V, or 24 V rail. The rail-to-rail output swings to within millivolts of each rail, which is exactly what you need for single-supply ADC interfaces.
Yes, the output type is rail-to-rail. That means the output can swing to within a few millivolts of the positive and negative supply rails, maximizing the usable signal range in low-voltage single-supply designs.
The gain-bandwidth product is 10 MHz. Combined with a 10 V/µs slew rate, this op-amp can handle signals up into the low-MHz range for active filters, ADC drivers, and fast control loops.
A close functional peer is the TLV9351IDCKR — same single-channel, rail-to-rail, general-purpose op-amp in the same SC-70-5 footprint. The TLV9351 offers a higher slew rate (20 V/µs) and lower input bias current (10 pA) but a slightly lower gain-bandwidth (3.5 MHz). Check the supply voltage and bandwidth requirements of your circuit before swapping.
