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.
