General Description  
The DAT-15575-PN is a 75Ω RF digital step attenuator that offers an attenuation range up to 15.5 dB in  
0.5 dB steps. The control is a 5-bit parallel interface, operating on dual supply voltage: VDD=+3V, VSS=-3V.  
The DAT-15575-PN is produced using a unique CMOS process on silicon, offering the performance of  
GaAs, with the advantages of conventional CMOS devices.
