Product details

350 kHz gain-bandwidth, 20 µA supply — the micropower trade-off

The OPA347UA/2K5 is a single general-purpose op amp from Texas Instruments that trades bandwidth for supply current. The 350 kHz gain-bandwidth product and 0.17 V/µs slew rate place it firmly in the micropower category — it is not a high-speed amplifier. The 20 µA supply current (typical) is the reason this part exists: it lets a sensor- conditioning stage run continuously on a battery without draining it.

This part is not AEC-Q100 qualified.

17 mA output current — driving the load within limits

Output current is 17 mA per channel. Supply current is 20 µA.

8-SOIC package — the standard footprint

Package is 8-SOIC with 0.154" body width, surface mount.

Frequently asked questions

Is OPA347UA/2K5 RoHS compliant?

Yes, OPA347UA/2K5 is ROHS3 Compliant.

What is OPA347UA/2K5's slew rate?

The slew rate is 0.17 V/µs. This is a low slew rate consistent with the micropower design — it limits the large-signal bandwidth to about 27 kHz at 3.3 V swing. For amplifying fast edges or high-frequency signals above 50 kHz, a faster op-amp is needed.
