MAADSS0010
Digital Attenuator, 5-Bit, 31 dB
400 - 2500 MHz
Lead-Free QSOP-16 (SSOP-16)^†
Rev. V2
† Reference Application Note M538 for lead-free solder reflow recommendations.
Recommended Configuration
Operating Instructions
The MAADSS0010 is designed to operate with 5 V
logic levels. The difference between +3 V and +5
V operation is minimal for small signal perform-
ance. IIP3, however, is a strong function of volt-
age. +3 V is the minimum voltage at which the
product will reliably operate.
The MAADSS0010 requires a parallel interface that
allows the user to enter a 5 bit digital word. Each
state increments the attenuation by 1.0 dB giving a
total range of 31 dB.
The MAADSS0010 is not internally DC blocked.
This means that the device requires DC blocking
10 KΩ
capacitors on the RF1 and RF2 ports. M/A-COM
recommends 0.1 uF to allow for the entire fre-
quency range to be utilized. Higher frequency
applications can use smaller value capacitors as
DC blocks.
