ADIADM3202ARNZ
Overview
The ADM3202ARNZ is a dual-channel RS-232 line driver and receiver designed for high-speed communication up to 460Kbps. It operates from a single 3V to 5.5V supply using four small external 0.1uF charge pump capacitors. This transceiver is robust against electrostatic discharge, featuring IEC 1000-4-2 protection up to +/-15kV on the RS-232 interface pins.
Why Choose This Part
The part offers superior ESD protection with +/-15kV air gap discharge rating, reducing the need for external TVS diodes. Its wide 3V to 5.5V supply range allows it to interface directly with both modern low-voltage MCUs and legacy 5V systems without level shifting.
Applications
Key Specifications
Getting Started
To use this device, connect four 0.1uF capacitors to the internal charge pump pins (C1+/C1- and C2+/C2-) to generate the required RS-232 voltage levels. Ensure the SOIC-16 footprint includes bypass capacitors near the VCC pin to minimize switching noise.
