10.1 Layout Guidelines

Use good high-frequency printed circuit board (PCB) layout techniques for the OPA357. Generous use of ground planes, short and direct signal traces, and a suitable bypass capacitor located at the V+ pin assures clean, stable operation. Large areas of copper also provide a means of dissipating heat that is generated in normal operation.

Sockets are definitely not recommended for use with any high-speed amplifier.

A 10-nF ceramic bypass capacitor is the minimum recommended value; adding a 1-μF or larger tantalum capacitor in parallel can be beneficial when driving a low-resistance load. Providing adequate bypass capacitance is essential to achieving very low harmonic and intermodulation distortion.
