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. * M suffix denotes welded metal package instead of standard epoxy sealed ceramic package.
