Overload LED
The amplifier features a LED to signalize an overload condition. The Overload LED will turn on
if the signal level within the signal path exceeds the linear operating range. In order to ensure
the correct operation of the amplifier without signal distortions reduce the gain setting until
the Overload LED turns off.
The Overload LED may also turn on under the following operating conditions:
- The amplifier is operated with open input or with a high source impedance. For proper
operation please use a source impedance of less than 100 M
Ω or switch to a lower gain
setting.
- When using a DLPVA-F-D with differential input stage the Overload LED may turn on if the
common mode input voltage exceeds ± 5 V or if the source is totally floating with respect to
the amplifier ground. For proper operation make sure that the common mode voltage stays
within ± 5 V with respect to the amplifier ground and make a valid connection between the
source ground and the amplifier ground to ensure that the inputs cannot drift outside the
tolerable common mode range.
