Layout, Decoupling, and Grounding Considerations
Layout, Decoupling, and Grounding
Considerations
Proper grounding and layout of the PCB is essential to achieve the stated
performance. It is advised to use separate analog and digital ground planes
that are spliced underneath the device. The THS0842 has digital and analog
terminals on opposite sides of the package to make this easier. Since there is
no internal connection between analog and digital grounds, they have to be
joined on the PCB. This should be done at one point in close proximity to the
THS0842.
Separate analog and digital power-supply terminals are provided on the
device (AV
DD
/DV
DD
). The supply to the digital-output drivers (DRV
DD
) is also
kept separate. Lowering the voltage on this supply to 3 V instead of the nominal
3.3 V improves performance due to the lower switching noise caused by the
output buffers.
Because of the high sampling rate and switched-capacitor architecture, the
THS0842 generates transients on the supply and reference lines. Proper
decoupling of these lines is essential. Decoupling as shown in the schematic
of the THS0842 EVM is recommended.
