Design a Custom BoardDual-channel precision CMOS operational amplifier featuring low noise (2.7 nV/√Hz at 10 kHz) and low offset voltage (250 µV max). Operates from 2.7 V to 5.5 V with rail-to-rail input/output, 28 MHz bandwidth, and unity gain stability. Ideal for ADC/DAC buffers, audio pre-amplifiers, precision filters, and automotive applications including collision avoidance systems.
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.
