Overview
The ADM3488ARZN from Analog Devices Inc. is a low-power, differential line transceiver designed for RS-485 and RS-422 communications. This full-duplex transceiver operates on a single 3.3 V power supply, making it ideal for power-sensitive applications. It features slew rate limited drivers to minimize EMI and reduce reflections caused by improperly terminated cables, ensuring error-free data transmission up to 250 kbps. The device includes thermal shutdown and current limit protection to prevent excessive power dissipation and output current during fault conditions.
