*Select the inductors to ensure that self-resonance of the inductors is outside the band of operation.
The sequence to be used is:
1) Power supply
2) Control lines
The pin configuration of the device is optimized to facili-
tate a very compact physical layout of the device and its
associated discrete components. The exposed pad (EP)
of the device’s 48-pin TQFN-EP package provides a low
thermal-resistance path to the die. It is important that

DESCRIPTION
the PCB on which the device is mounted be designed
to conduct heat from the EP. In addition, provide the EP
with a low inductance path to electrical ground. The EP
MuST be soldered to a ground plane on the PCB, either
directly or through an array of plated via holes. The lay-
out of the PCB should include proper top-layer ground
shielding to isolate the amplifier’s inputs and outputs
from each other. Shielding between the paths (inputs and
outputs) is important for channel-to-channel isolation.
