e) Socketing a high-speed part such as the
THS6214 is not recommended. The additional lead
length and pin-to-pin capacitance introduced by the
socket can create an extremely troublesome parasitic
network, which can make it almost impossible to
achieve a smooth, stable frequency response. Best
results are obtained by soldering the THS6214
directly onto the board.
f) Use the –V_S plane to conduct heat out of the
QFN-24 and TSSOP-24 PowerPAD packages. These
packages attach the die directly to an exposed
thermal pad on the bottom, which should be soldered
to the board. This pad must be connected electrically
to the same voltage plane as the most negative
supply applied to the THS6214 (in Figure 82, this
supply is –12V).
