Design a Custom BoardAbout This Component
Low-noise, fully-differential audio operational amplifier with 3.7 nV/√Hz input voltage noise and –120 dB THD+N at 1 kHz. Features 9.2 MHz gain-bandwidth product, ±18 V supply capability, and 950 µA quiescent current. Ideal for high-fidelity audio mixers, professional microphones, ADC drivers, and low-power audio signal conditioning applications.
Package: MSOP-8 · 8 pins
Why does this need a breakout?
The 0.65mm pitch and tiny 3×3mm form factor make hand soldering challenging and impractical for breadboard prototyping. A breakout board converts this compact SMD package into a standard header layout, enabling reliable connections and rapid iteration without specialized soldering equipment or rework risk.
