ARA3000 S23 -40 to +850 C
28 PIN SSOP PACKAGE
Description
The ARA3000 is a GaAs IC designed to provide additional reverse path amplification and isolation in IP
Telephony Systems. The precision step attenuator can be digitally controlled to set the output power to the
desired level. The single amplifier stage at the output is capable of meeting both the DOCSIS distortion and
noise requirements from a single +5V supply. In addition, the output amp can be shut down and bypassed
by an on chip switch to save power. The ARA3000 is supplied in a 28-pin SSOP package featuring an
exposed paddle on the bottom of the package. Soldering the exposed paddle to the ground plane of the PC
board ensures the lowest possible thermal resistance for the IC resulting in a long MTF.
