OPA137NA/3K Description

Short technical summary and product information.

The OPA137NA/3K from Texas Instruments is a single operational amplifier designed for low-cost and miniature applications. This FET-input amplifier offers a low input bias current of ±10pA and a low quiescent current of 120µA per channel. It boasts a high open-loop gain of 145dB and a bandwidth of 1.1MHz, making it suitable for various audio and general-purpose applications.

The OPA137NA/3K supports a wide supply voltage range, accepting either single supplies from +4.5V to +36V or dual supplies from ±2.25V to ±18V. The input common-mode voltage range includes the positive supply, which is advantageous for many single-supply applications. The device is available in a compact SOT-23-5 package, suitable for space-constrained designs.

This operational amplifier is designed for ease of use, avoiding phase inversion and overload issues common in some FET-input amplifiers. Its specifications are identical across single, dual, and quad versions, providing design flexibility. The operating temperature range is -40°C to 85°C.
