Description

M/A-COM's AT65-0283 is a GaAs FET 5-bit digital

attenuator with integral TTL driver. Step size is 0.5 dB

providing a 15.5 dB total attenuation range. This device is

a SOIC-16 plastic surface mount package. The

AT65-0283 is ideally suited for use where accuracy, fast

speed, very low power consumption and low costs are

required.

Package outline conforms to JEDEC standard MS-013AA.

Electrical Specifications: T_A= 25°C
