Description

M/A-COM’s AT65-0413 is a GaAs FET 4-bit digital

attenuator with a 1.0 dB minimum step size and a 15 dB

total attenuation range. This device is in a SOIC-16 plastic

surface mount package. The AT65-0413 is ideally suited for

use where accuracy, fast speed, very low power

consumption and low costs are required. Typical

applications include dynamic range setting in precision

receiver circuits and other gain/leveling control circuits.

Electrical Specifications: T_A= 25°C
