Description
M/A-COM's AT90-0283 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 an FQFP-N plastic surface mount package. The AT90-
0283 is ideally suited for use where accuracy, fast speed,
very low power consumption and low costs are required.
