This attenuator and integral TTL driver is in a hermetically sealed ceramic 24- lead surface mount package. The AT-107-PIN is ideally suited for use where accuracy, fast switching, very low power consumption and low intermodula- Pin Configuration tion products are required. Typical applications in- clude dynamic range setting in precision receiver Pin No. Function Pin No. Function circuits and other gain/leveling control circuits.
