SM16Z4689 E3

SM16Z4689, e3 HEX-RegTM 5.1 Volt Zener Diode Array for Hex Attenuator Drivers SCOTTSDALE DIVISION The SM16Z4689 is designed for supplying the 5 volt bias at 50 μA for hex attenuator driver components. These provide the controlling voltage for 6-bit digital GaAs attenuators such as the Hittite HMC424LP3. This low current, 50 μA 5.1V zener array provides the necessary bias for the High State, 4.2 – 5.0 V, conditions when it triggers the associated driver. The HEXRegTM voltage regulator array is supplied in the SO-16 package with two spare diodes for applications requiring up to eight diodes. A suggested driver circuit in figure 1 illustrates one of the six inputs to a 6-bit attenuator. SO-16 Package WWW .
