Technical details

Low-power, rail-to-rail general-purpose op amp in a through-hole DIP

It delivers a 1 MHz gain-bandwidth product with a 0.6 V/µs slew rate, drawing just 160 µA of supply current. Input bias current is a CMOS-typical 1 pA, so it won't load high-impedance sensors.

That's fine for audio, sensor conditioning, and low-speed control loops, but not for video or fast ADC drivers. The 1 MHz gain-bandwidth product supports gains up to 100 with a 10 kHz closed-loop bandwidth — adequate for most precision analog front-ends. If you need to drive a 10-bit ADC at 100 kSPS, the settling time from this amplifier will be the bottleneck; consider a faster part like the TLV9351 (3.5 MHz, 20 V/µs) for that role.
