Analog Devices ADM202/ADM203 RS-232 Line Driver/Receiver Datasheet Rev A
The ADM202/ADM203 is a two‑channel RS‑232 line driver/receiver designed for operation from a single 5 V supply. It uses an on‑chip charge‑pump to generate ±10 V RS‑232 levels, supports up to 120 kB data rates, and includes over‑voltage and ESD protection. The ADM202 version requires external charge‑pump capacitors, while the ADM203 integrates them internally.
The datasheet provides detailed specifications such as output voltage swing (±5 V to ±9 V typical), input logic thresholds (0.8 V low, 2.4 V high), power‑supply current (2.5‑6.0 mA), and pin functions. Mechanical drawings for DIP and SOIC packages are also included.
