Introduction

The DAT- 31R5A+ series of 50Ω digital step attenuators provides adjustable attenuation from 0 to 31.5 dB in 0.5 dB steps. The control is a 6- bit serial/parallel interface, and the attenuators operate with either single positive or dual (positive and negative) supply voltage. DAT- 31R5A+ series models are produced by a unique CMOS process on silicon, offering the performance of GaAs with the advantages of conventional CMOS devices. The DAT- 31R5A- SP+ is a 50Ω digital step attenuator that provides adjustable attenuation of 0 to 31.5 dB in 0.5 dB steps. The control is a 6- bit serial interface, operating with a single (positive) supply voltage. DAT- 31R5A- SP+ is produced by a unique CMOS process on silicon, offering the performance of GaAs with the advantages of conventional CMOS devices.
