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.
