Overview
The ADM232AARWZ is a high-speed RS-232 line driver/receiver produced by Analog Devices Inc. This component is part of the ADM222, ADM232A, and ADM242 family, which offers advanced features for high-speed data transmission. Operating from a single 5 V power supply, the ADM232AARWZ integrates a highly efficient on-chip charge pump that generates the necessary RS-232 bipolar levels using small external capacitors. This device is fabricated using BiCMOS technology, combining low power CMOS with high-speed bipolar circuitry, enabling transmission rates up to 200 kB/s while minimizing power consumption.
