The DAT-15R5A+ series of 50Ω digital step attenuators provides adjustable attenuation of 0 to 15.5 dB in 0.5 dB steps. The control is a 5-bit serial interface, and the attenuator operates with dual (positive and negative) supply voltage. DAT-15R5A-SN+ is produced using a CMOS process on silicon, offering the performance of GaAs with the advantages of conventional CMOS devices.
