Uart Interface - Analog Devices EZ-Board ADSP-BF518F Manual

The ADC range is controlled by jumper
the input range for the ADC is 2.5V or 5 V. The max voltage range for a
signal connected to the SMA connector is 0–5V. Any voltage outside of
this range can damage the EZ-Board.

input. When there is no input connected to the SMA connector, the
jumper should have the shunt installed on pins 2&3. This setting con-
nects the signal going to the ADC input to ground and keeps the noise
level low. When an input signal is connected to the SMA connector, the
shunt should be installed on position 1&2.
