Overview
The ADM232AARNZ is a high-speed RS-232 line driver/receiver produced by Analog Devices Inc. It is part of the ADM222, ADM232A, and ADM242 family, designed to operate at transmission rates up to 200 kB/s. This device is fabricated using BiCMOS technology, combining low power CMOS with high-speed bipolar circuitry, which enables efficient operation with minimal power consumption.
Operating from a single 5 V power supply, the ADM232AARNZ integrates an on-chip charge pump that uses small external capacitors (0.1 µF) to generate the necessary RS-232 bipolar levels. This component is available in various package types, including 16-lead DIP and both narrow and wide surface-mount (SOIC) packages.
