OPA2140AID Description

Short technical summary and product information.

The OPA2140AID from Texas Instruments is a high-precision, low-noise JFET operational amplifier designed for demanding applications. This dual-channel amplifier features an 11-MHz gain bandwidth product and a 20 V/µs slew rate, enabling fast and accurate signal processing.

 

It offers excellent DC precision with a low offset voltage of 120 µV maximum and a very low offset drift of 1 µV/°C maximum. The low input bias current of 10 pA maximum and low noise characteristics (5.1 nV/√Hz at 1 kHz) make it suitable for sensitive measurement and audio circuits.

 

The OPA2140AID supports a wide supply voltage range, from 4.5V to 36V for single-supply operation and ±2.25V to ±18V for dual-supply operation. It provides rail-to-rail output swing, maximizing dynamic range. The amplifier is available in industry-standard packages including VSSOP, SOIC, and WSON.

 

This precision op-amp is well-suited for applications requiring high accuracy and low noise, such as audio equipment, sensor amplifiers, and active filters.
