MAX253CSA+T Description

Short technical summary and product information.

The MAX253CSA+T is a monolithic oscillator and power-driver IC from Analog Devices, specifically engineered to provide isolated power for RS-485 or RS-232 data interfaces. This device drives a center-tapped transformer primary using a single 5V or 3.3V DC power supply, enabling the secondary to provide any required isolated voltage up to 1W.

Key electrical characteristics include a supply voltage range of 3.3V to 5V and a low supply current of 450µA. The operating temperature range is from 0°C to 70°C. The MAX253CSA+T is housed in an 8-SOIC package, suitable for surface mount applications.

This component is ideal for applications requiring high noise-immunity communications interfaces, isolated and/or high-voltage power supplies, and bridge ground differentials. Its design facilitates simple power-supply transformer driver configurations for isolated data interfaces.
