Overview
The ADM238LJNZ, produced by Analog Devices Inc., is a low-power, +5V CMOS RS-232 transceiver designed for a wide range of serial communication applications. This device is part of the ADM2xx family and is particularly suited for environments where a single 5V power supply is available, eliminating the need for external voltage sources. The ADM238LJNZ features on-board DC-DC converters that generate the necessary ±10V output swing from a single 5V supply, making it highly efficient and compact.
