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.
