Product details

What this op-amp brings to a signal chain

The Texas Instruments OPA344UA/2K5 is a single-channel, general-purpose CMOS op-amp from the MicroAmplifier™ family. It delivers a 1 MHz gain-bandwidth product and a 0.8 V/µs slew rate.

Gain bandwidth and slew rate — where the part fits

Rated for -40°C to 85°C, this part handles outdoor telecom cabinets, factory-floor sensor enclosures, and engine-bay-adjacent electronics that stay below the 85°C mark.

The OPA344UA/2K5 carries an Active lifecycle status and is ROHS3 compliant.

Frequently asked questions

What is the gain bandwidth product of OPA344UA/2K5?

The gain bandwidth product is 1 MHz.

Is the OPA344UA/2K5 a rail-to-rail op amp?

Yes, the output type is rail-to-rail.

What are equivalent parts to OPA344UA/2K5?
