MAX253ESA+ Description

Short technical summary and product information.

The MAX253ESA+ by Analog Devices is a monolithic oscillator and power-driver specifically engineered to provide isolated power for RS-485 or RS-232 data interfaces. This device drives a center-tapped transformer primary from a 5V or 3.3V DC power supply, enabling the secondary to provide any isolated voltage up to 1W.

 

Key features include pin-selectable frequencies of 350kHz or 200kHz and a low-current shutdown mode drawing only 0.4µA. The MAX253ESA+ operates within a temperature range of -40°C to 85°C and is housed in an 8-SOIC package, making it suitable for applications requiring high noise immunity and isolated power supplies.

 

This component is ideal for applications such as isolated power supplies, high noise-immunity communications interfaces, and bridging ground differentials. Its design simplifies the creation of isolated power supply transformer driver circuits for data interfaces.
