ADDITIONAL DEVICES OF INTEREST
While we won't test these circuits and devices, they are worth discussing.
Darlington-Pair Drivers
Just as a Darlington-pair may be used to detect small signals, as explored with the opto-
reflective switch, they may also be used as high current drives. The ULN2003A shown
in Figure 5-22 is a popular device in that it contains seven drivers, each capable of
sinking 500 mA at 50 V.
