Product details

Signal chain fit: 5.5 MHz GBW and rail-to-rail output

The OPA340NA/250 is a single-channel general-purpose op-amp from TI's MicroAmplifier™ series, offering a 5.5 MHz gain-bandwidth product and 6V/µs slew rate in a SOT-23-5 package.

The SOT-23-5 package supports 50 mA output per channel, enough to drive an ADC input or a low-power actuator directly.

No successor part is listed, so this remains the current production variant for the single-channel, SOT-23-5 footprint. For dual-sourcing, a pin-compatible alternative within the same family may exist — confirm the package and supply voltage match before substituting.

Frequently asked questions

Can OPA340NA/250 be used in audio applications?

With a 5.5 MHz gain-bandwidth and 6V/µs slew rate, the OPA340NA/250 can handle audio-band signals up to roughly 20 kHz with adequate loop gain. The 150 µV input offset and rail-to-rail output are suitable for line-level audio paths, though the 0.2 pA input bias is more relevant for high-impedance sensor interfaces than audio.
