Product Description
The Texas Instruments OPA604AU is a precision JFET input operational amplifier engineered for high-accuracy analog applications. Providing a 20MHz gain bandwidth product, this IC is well suited for audio processing, high-speed signal acquisition, and professional instrumentation. It delivers excellent linearity and fast response due to its 25V/μs slew rate, ensuring minimal distortion in dynamic signal paths.
This device operates across a wide supply range of ±4.5V to ±25V, accommodating both low- and high-voltage environments found in industrial, laboratory, and audio electronic systems. The low input bias current of 50pA allows for accurate measurements in high-impedance circuits, while the ±5mV input offset voltage ensures minimal drift and consistent performance.
The OPA604AU is encapsulated in a standard 8-pin SOIC (Small Outline Integrated Circuit) package, facilitating surface mount assembly in compact PCB layouts. Its single-channel configuration, 35mA maximum output current, and ±3pA input offset current make it adaptable for precision buffer, filter, or amplification stages.
Designed for harsh environments, this amplifier is specified for operation from -25°C to +85°C, maintaining stability and reliability under fluctuating ambient temperatures. It is compliant with RoHS standards, allowing integration into modern environmentally regulated products.
Common use cases for this Operational Amplifier include signal conditioning in test and measurement equipment, high-fidelity audio amplifiers, sensor interfaces, and other applications where low noise, high gain, and excellent linearity are required. Its robust construction and consistent parameters make it a staple in laboratory, industrial, and engineering development environments.
With its combination of high speed, low noise, and flexible power supply compatibility, the Texas Instruments OPA604AU is suitable for demanding analog system designs seeking both performance and reliability.
