Présentation

Description

The ADM232AARWZ is a dual RS-232 line driver/receiver from Analog Devices, designed for serial communication. It operates from a single +5V supply, making it suitable for interfacing with microcontrollers and UARTs. Key features include:
- Dual-channel operation (two transmitters and two receivers).
- ±30V input tolerance for robust signal handling.
- Low power consumption (typically 5mA supply current).
- Compliant with EIA-232-F standards.
It converts TTL/CMOS logic levels to RS-232 voltage levels (±5V to ±15V) and vice versa, ensuring reliable data transmission over short distances. The device is commonly used in industrial control, telecom, and embedded systems.
Packaged in a 16-pin SOIC, the ADM232AARWZ is pin-compatible with older RS-232 transceivers like the MAX232, offering a modern alternative with improved performance.
For detailed specs, refer to the datasheet on Analog Devices' website.
