ADM3491 Datasheet PDF

●GENERAL DESCRIPTION

●The ADM3483/ADM3485/ADM3488/ADM3490/ADM3491 are low power, differential line transceivers designed to operate using a single 3.3 V power supply. Low power consumption, coupled with a shutdown mode, makes the ADM3483/ADM3485/ADM3488/ADM3490/ADM3491 ideal for power-sensitive applications.
