General Description
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.
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.
