FIGURE 6. Model 540 Connected For Current-Sourcing Mode
Figure 6 shows the connections for current-source operation.
In this mode the Model 540 is short-circuit protected for +VS
of +5V to +15V. If short-circuit and current limiting protection
is desired for +VS of +16V to +32V, a 100
2W resistor should
be connected between +Vs and pin 1. Output voltage in the
current-source mode is +V
S - (3.5V + 10
I
L). Figure 7 is a
graph of output voltage versus load current for current source
operation. Output leakage does not exceed 1 mA.
FIGURE 4. Model 540 Connected For Current-Sinking Mode
The connections for current-sinking operation are shown
above in Figure 4. In this mode the Model 540 is short-circuit
protected and current-limited at 140 mA. The diode across
the output transistor protects the transistor against possible
back bias. Of the two output modes, current-sinking is more
desirable because there is less power dissipation in the low
output state. When the voltage at the NON INVERTING input
is more positive than the voltage at the INVERTING input, the
IC comparator switches to the high logic state. This causes
the output transistor to saturate, which will then energize the
load. Figure 5 is a graph of output voltage versus load current
for the saturated output transistor. Output leakage does not
exceed 1 mA.
