Typical use includes high-impedance sources and low-noise amplification.

## Long description

Dual operational amplifier Texas Instruments OPA2340EA/2K5 is a precision JFET-input op amp packaged as a dual-channel device. The OPA2340 family is designed for low input bias current and low offset voltage while providing adequate bandwidth for a variety of signal conditioning tasks. It is suitable for interfacing with high-impedance sources and for low-noise amplification in instrumentation, audio and industrial electronics.
Advantages
The device combines JFET-input characteristics with dual-channel integration, offering low input bias current and low offset voltage that reduce measurement error when connected to high-impedance sensors. Its low noise performance and stable gain behavior across a useful frequency range make it appropriate for precision amplification and active filter stages. The dual configuration conserves board space and simplifies symmetric circuit designs.
Suitable for
 Signal conditioning and sensor front-ends
 High-impedance source buffering
 Precision amplification in instrumentation
 Active audio filters and preamplifiers
 Industrial control and measurement circuits
Key specifications
 Dual op amp configuration (two amplifiers in one package)
 JFET-input stage providing low input bias current
 Low input offset voltage for precision measurements
 Low noise suitable for sensitive analog signal paths
 Wide bandwidth adequate for common signal conditioning and filter applications
 Industry-standard DIP/SMD package options for PCB mounting
How to use
Integrate the dual op amp into your circuit following standard analog design practices: provide appropriate supply rails as specified by the manufacturer, decouple the power pins with bypass capacitors close to the device, and design feedback networks for the required gain and bandwidth. For sensor interfaces, use the JFET-input amplifier as a buffer or in low-noise gain stages, ensuring input sources are protected from large transient voltages. Match resistor values and feedback topology to maintain stability and performance across temperature and supply variations.
Usage recommendations
Use short, low-impedance PCB traces for input and feedback paths, place decoupling capacitors close to the supply pins, and follow recommended layout guidelines for analog precision circuitry to minimize noise and offset. When interfacing with very high-impedance sensors, consider input protection and guarding techniques to preserve measurement accuracy.
