Description
M/A-COM's AT65-0263 is a GaAs FET 5-bit digital
attenuator with integral TTL driver. Step size is 1.0 dB
providing 31 dB total attenuation range. This device is in a
SOW-16 plastic surface mount package. The AT65-0263 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
