FEATURES
Two AD8224 circuits
Dual channel
Differential output
Easy to connect screw terminals
Decoupled supply lines
Pads for RFI filtering
GENERAL DESCRIPTION
The AD8224-EVALZ has two
amplifier circuits: one circuit is configured for dual-channel
operation, and the other is configured for single-channel,
differential output operation. The inputs, outputs, references,
and supplies are routed to screw terminals for easy connectivity.
The PCB board has four layers. The top and bottom layers are
used for routing, and the two internal layers are ground planes.
The ground plane was removed underneath the R
G
resistors.
This is a precaution against any capacitance mismatch at the
RGx pins that may affect ac CMRR.
