AA220-25

GaAs IC 4 Bit Digital Attenuator 2 dB LSB DC–2 GHz AA220-25 (Previously AD220-25)* Features I Attenuation in 2 dB Steps to 30 dB with High Accuracy I Low Cost SOIC-16 Plastic Package I Low DC Power Consumption SOIC-16 PIN 16 0.050 (1.27 mm) BSC PIN 1 INDICATOR 0.244 (6.20 mm) 0.228 (5.80 mm) Description The AD220-25 is an IC FET digital attenuator consisting of four monolithic attenuators with LSB of 2 dB and a total attenuation of 30 dB with all attenuators connected. The AD220-25 is particularly well 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.
