    DAT-31R5A-PP+   Digital Step Attenuator   50Ω 0 to 31.5 dB, 0.5 dB Step DC to 4.0 GHz

The Big Deal

• Wideband, operates up to 4 GHz

• Immune to latchup

• High IP3, 52 dBm

Product Overview

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.
