High Speed Drivers
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.
1. W hen using inverting input, connect bias pin 5 to
2. W hen using non-inverting input, connect bias pin 5
3. For -30 mA output current, connect pin 8 to pin 9.
4. For positive output currents other than 15 mA or
5. The negative output current varies with V ee and is

Dual High Speed Drivers
A dual DD111 with current programming pins
omitted. This driver is often used in SPDT applications
by driving the inverting input of one channel and the

a resistor from TP- (pin 14) to V ee (pin 1). See figure.
