GROUNDING AND BYPASSING
The LTC2258-12/LTC2257-12/LTC2256-12 requires a
printed circuit board with a clean unbroken ground plane.
A multilayer board with an internal ground plane is rec-
ommended. Layout for the printed circuit board should
ensure that digital and analog signal lines are separated 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 at
the VDD, OVDD, VCM, VREF, REFH and REFL pins. Bypass
capacitorsmustbelocatedasclosetothepinsaspossible.
Of particular importance is the 0.1F capacitor between
REFH and REFL. This capacitor should be on the same
side of the circuit board as the A/D, and as close to the
device as possible (1.5mm or less). Size 0402 ceramic
capacitors are recommended. The larger 2.2F capacitor
between REFH and REFL can be somewhat further away.
The VCM capacitor should be located as close to the pin
as possible. To make space for this the capacitor on VREF
can be further away or on the back of the PC board. The
traces connecting the pins and bypass capacitors must
be kept short and should be made as wide as possible.
The analog inputs, encode signals, and digital outputs
should not be routed next to each other. Ground fill and
grounded vias should be used as barriers to isolate these
signals from each other.
HEAT TRANSFER
Most of the heat generated by the ADC is transferred from
the die through the bottom-side exposed pad and package
leadsontotheprintedcircuitboard.Forgoodelectricaland
thermal performance, the exposed pad must be soldered
to a large grounded pad on the PC board.
