Description
M/A-COM's AT90-0263 is a GaAs FET 5-bit digital
attenuator with integral TTL driver. Step size is 1.0 dB
providing 31dB total attenuation range. This device is in a
FQFP-N plastic surface mount package. The AT90-0263 is
ideally suited for use where accuracy, fast speed, very low
power consumption and low costs are required.
