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.  
Electrical Specifications: TA = 25°C
