Features, Applications


Attenuation 4 dB steps 28 dB with High Accuracy Low Cost SOIC-14 Plastic Package Low DC Power Consumption


The an IC FET digital attenuator consisting of three monolithic attenuators with LSB 4 dB and a total attenuation 28 dB with all attenuators connected. Attenuators are switched with -5 and 0 V. The AA230-24 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.
