APPLICATIONS INFORMATION
as much as possible. In particular, care should be taken
not to run any digital track alongside an analog signal
track or underneath the ADC.
High quality ceramic bypass capacitors should be used

Grounding and Bypassing
The LTC2208-14 requires a printed circuit board with a
clean unbroken ground plane; a multilayer board with an
internal ground plane is recommended. The pinout of the
LTC2208-14 has been optimized for a fl owthrough layout
so that the interaction between inputs and digital outputs
is minimized. Layout for the printed circuit board should
ensure that digital and analog signal lines are separated

pins. Bypass capacitors must
connecting the pins and bypass capacitors must be kept
short and should be made as wide as possible.
The LTC2208-14 differential inputs should run parallel and
close to each other. The input traces should be as short as
possible to minimize capacitance and to minimize noise
pickup.
Heat Transfer
Most of the heat generated by the LTC2208-14 is trans-
ferred from the die through the bottom-side exposed pad.
For good electrical and thermal performance, the exposed
pad must be soldered to a large grounded pad on the PC
board. It is critical that the exposed pad and all ground
pins are connected to a ground plane of suffi cient area
with as many vias as possible.
