Figure 2 illustrates how the 722 can provide isolated input
power to the input stage of two 3650s connected in the two-
port configuration. Power for the output stage is provided by
the system +15V and
–
15V supplies. Input stages are iso-
lated from each other and from the system supply. In this
situation, the 722 input-to-output isolation specification ap-
plies to the amplifier input-to-output voltages, whereas the
channel-to-channel 722 specification applies to the voltage
existing between I/P Com #1 and I/P Com #2.
SHORT CIRCUIT PROTECTION
The circuit in Figure 3 may be added to the input of the 722
to protect it from damage in situations where too much
current is demanded from the outputs
—
such as a short
circuit from an output to its common. The circuit limits input
current to approximately 150mA for an input voltage of
15VDC (for
of 2N2219 of 50).
