3.4 Mounting the Guitar The Guitar was designed for mounting on a printed circuit board (PCB). It is connected by 2 mm pitch 0.51 mm square pins. When designing the Guitar into a device, be sure to leave about 1 cm (0.4") outward from the heatsink to enable free air convection around the Guitar.
3.5 Integrating the Guitar on a PCB The Gu itar is designed to be mounted on a PCB, either by sold ering its pins directly to the PCB or by using sui table socket connectors.
2. Inputs : The 6 inputs are optically isolated from the other parts of the Guitar. Each input has a separate floating return (INRET1 for input 1 and INRET2 for input 2, etc.) . To retain isolation, the Input Return pins, as well as other conductors on the input circuit, must be laid out separately.
