Working Principles

The ADM3202ARU is designed to facilitate communication between a microcontroller or microprocessor and an RS-232 interface. It utilizes a charge pump to generate the required voltage levels for RS-232 communication. The transceiver receives serial data from the microcontroller, converts it into RS-232 levels, and transmits it to the RS-232 interface. Similarly, it receives RS-232 data from the interface, converts it into logic levels, and sends it to the microcontroller.

Detailed Application Field Plans

The ADM3202ARU is commonly used in various applications that require RS-232 communication, such as:

1. Industrial automation systems
2. Data acquisition systems
3. Point-of-sale terminals
4. Networking equipment
5. Medical devices
6. Test and measurement instruments
