Problem reading or writing the
LMH2832 device using the LMH2832
EVM GUI:
Verify that the green USB Status indicator is lit in the top
right corner of the GUI. If it is not lit, click the
Reconnect USB
button and check the
USB Status
indicator again. If it is still
not lit, then verify the EVM is connected to the computer
through the included mini-USB cable.
Check to see whether the connectors to power supply pins of
the LMH2832 EVM are connected properly and turned ON.
The nominal supply current for the LMH2832EVM for 5-V
supply is approx 204-mA with both the channels enabled.
Low supply current:
See if one of the device channels is disabled by the PDA or
PDB jumper. Also, check to see if the power supply is set to
the right voltage.
No supply current:
See if the power supply cable connections are connected
and the power switch of the source is turned ON.
High supply current:
The reverse supply protection diodes may be conducting.
Turn off the power switch and make sure the positive supply
is connected to the proper pin. Turn the power back on to
see if the correct supply current is recorded.
