HIGH SPEED DRIVERS
DD111
DD111M*
A universal PIN diode driver with excellent noise
immunity, very fast switching, 100 mA current
spikes and available test points for increasing
quiescent output current.
4. For positive output currents other than 15 mA or
30 mA , an external resistor can be connected
between pin 8 and +5V . See graph.
5. The negative output current varies with V ee and is
specified at -12 V . W hen driving grounded anode
diodes, V ee should be kept at -5 V where the negative
current will be 5 mA . It may be increased by connecting
a resistor from TP- (pin 14) to V ee (pin 1). See figure.
1. W hen using inverting input, connect bias pin 5 to
non-inverting input pin 6.
2. W hen using non-inverting input, connect bias pin 5
to inverting input pin 4.
3. For -30 mA output current, connect pin 8 to pin 9.
