CDB5480U
6 DS893DB5
The CDB5480U evaluation board provides screw-type terminal (J4) to connect to the high-voltage line
input. By installing jumpers on J6 to position LINE and J11 to position GND, the input voltage signal is
supplied from the high-voltage input. Extreme care should be used when connecting high-voltage signals
to the CDB5480U evaluation board (see Figure 3).
Figure 3. Voltage Channel — High-voltage Input
The on-board attenuation network provides the following attenuation:
With the CS5480 input range of 250mVp at maximum AC line input of:
is acceptable. It is recommended to apply a 10% margin for the AC line input (270V
rms
).
The CDB5480U evaluation board provides input shorting options for calibration and noise performance
measurements. With a jumper on J6 and J11 in the GND position, the inputs are connected to analog
ground (GND).
