Description and Introduction

Quad, Low-Power, Current Feedback Operational Amplifier The OPA4684 is a high-performance, quad-channel operational amplifier (op-amp) designed for precision applications requiring low noise, high speed, and wide bandwidth. Manufactured using advanced semiconductor technology, this component is well-suited for signal conditioning, data acquisition, and active filtering in industrial, medical, and communications systems.  

With a unity-gain bandwidth of 180 MHz and a slew rate of 450 V/µs, the OPA4684 ensures fast signal processing while maintaining excellent linearity. Its low input voltage noise of 4.3 nV/√Hz makes it ideal for sensitive measurements where signal integrity is critical. The op-amp operates over a wide supply voltage range (±2.5 V to ±6 V), providing flexibility in various circuit configurations.  

The OPA4684 features rail-to-rail output swing, maximizing dynamic range in low-voltage applications. Additionally, its low distortion and high common-mode rejection ratio (CMRR) enhance performance in differential signal processing. The quad-channel design allows for space-efficient PCB layouts, reducing component count in multi-channel systems.  

Engineers favor the OPA4684 for its robust performance in demanding environments, supported by a high electrostatic discharge (ESD) tolerance. Whether used in test equipment, audio processing, or control systems, this op-amp delivers reliable precision and speed, making it a versatile choice for modern electronic designs.
