Product Introduction

Overview

The ADM202EARU-REEL, produced by Analog Devices Inc., is a robust and high-speed 2-channel RS-232/V.28 interface device. This component is designed to operate from a single 5 V power supply, making it highly efficient and suitable for various applications. The ADM202EARU-REEL integrates step-up voltage converters and level-shifting transmitters and receivers, enabling it to meet the TIA/EIA-232-E and V.28 specifications. It features a highly efficient on-chip charge pump design that generates ±10 V RS-232 output levels using small external capacitors as small as 0.1 µF.
