OPA131UA Description

Short technical summary and product information.

The Texas Instruments OPA131UA is a single-channel FET-input operational amplifier designed for general-purpose applications. It features a low input bias current of 50pA maximum and a low offset voltage of 750µV maximum.

 

Key electrical characteristics include a gain bandwidth product of 4MHz and a slew rate of 10V/µs. The amplifier operates over a wide supply voltage range of ±4.5V to ±18V and a temperature range of -55°C to 125°C. It offers a typical output current of 0.025A and a low total harmonic distortion plus noise of 0.0008% at 1kHz.

 

The OPA131UA is available in a SOIC (D) surface-mount package with an area of 29.4 mm². Its FET input architecture makes it suitable for applications sensitive to input bias current.
