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.
