Overview
The ADM232LJNZ, produced by Analog Devices Inc., is a high-performance RS-232 transceiver integrated circuit designed for serial communication applications. This device operates from a single 5 V power supply and is capable of meeting all EIA-232-E and V.28 specifications. It features on-board DC-DC converters that generate the necessary ±10 V output swing from the 5 V supply, enabling full-duplex operation with two drivers and two receivers.
The ADM232LJNZ is particularly suited for applications where space is critical, thanks to its compact 16-SOIC package and surface mount design. It supports data rates up to 120 kB/s and operates within a wide temperature range of 0°C to 70°C.
