Description
M/A-COM's AT65-0106 is a GaAs FET 6-bit digital
attenuator with a 1 dB minimum step size and a 50 dB total
attenuation range. This device is in a SOIC-24, wide body
plastic surface mount package. The AT65-0106 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-013AD.
