Description
M/A-COM’s AT15-0001 is a GaAs FET 5-bit digital
attenuator with a 1-dB minimum step size and 31 dB
total attenuation. This attenuator and integral TTL driver
is in a 24-pin dual inline package. The AT15-0001 is
ideally suited for use where accuracy, fast switching,
very low power consumption and low intermodulation
products are required. Typical applications include
dynamic range setting in precision receiver circuits and
other gain/leveling control circuits.
Environmental screening is available. Contact the factory
for information.
