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. 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.
