Description
M/A-COM's AT65-0213 is a GaAs FET 4-bit digital
attenuator with a 1.0dB minimum step size and a 15 dB
total attenuation range. This device is in a SOIC-16 plastic
surface mount package. The AT65-0213 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.
Package outline conforms to JEDEC standard MS-013AA.
