DATA SHEET
AA210-25, AA210-25LF: GaAs IC 4-Bit Digital Attenuator
1 dB LSB 300 kHz–2 GHz
Features
● Attenuation 1 dB steps to 15 dB with high accuracy
● Low intermodulation products
● Low-cost SOIC-16 plastic package
● Low DC power consumption
● Available lead (Pb)-free and RoHS-compliant MSL-1 @ 260 °C
per JEDEC J-STD-020
Description
The AA210-25 is an IC FET digital attenuator consisting of four
monolithic attenuators with LSB of 1 dB and a total attenuation
of 15 dB with all attenuators connected. Attenuator bits are
switched with -5 and 0 V. The AA210-25 is particularly suited
where high attenuation accuracy, low insertion loss, and low
intermodulation products are required. Typical applications
include cellular, radio, wireless data, wireless local loop, and
other gain/level control circuits.
NEW Skyworks offers lead (Pb)-free, RoHS (Restriction of
Hazardous Substances)-compliant packaging.
