BOARD LAYOUT

To obtain the best performance from the LTC2369-18

a printed circuit board is recommended. Layout for the

printed circuit board (PCB) should ensure the digital and

analog signal lines are separated as much as possible. In

particular, care should be taken not to run any digital clocks

or signals alongside analog signals or underneath the ADC.

Recommended Layout

The following is an example of a recommended PCB layout.

A single solid ground plane is used. Bypass capacitors to

the supplies are placed as close as possible to the supply

pins. Low impedance common returns for these bypass

capacitors are essential to the low noise operation of the

ADC. The analog input traces are screened by ground.

For more details and information refer to DC1813A, the

evaluation kit for the LTC2369-18.
