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 in 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.
