The ADM3311EARS is an IC component manufactured by Analog Devices, which belongs to the ADM331x family of RS-232 interface devices. It is primarily designed to provide a complete interface solution for low-power applications that require RS-232 voltage levels to communicate with other devices.
Key Features:
1. Integrated Charge Pump: The ADM3311EARS features a built-in charge pump that generates the necessary voltage levels for RS-232 communication. This eliminates the need for external charge pump capacitors and greatly simplifies the design process.
2. Low Power Consumption: This IC is designed with low-power applications in mind, consuming only 25 μA of supply current during active operation. This makes it ideal for battery-powered devices where power consumption is a crucial factor.
3. ±15 kV ESD Protection: The ADM3311EARS provides robust protection against electrostatic discharge (ESD) events, with integrated circuitry capable of withstanding up to ±15 kV of ESD strikes on the RS-232 bus lines. This feature ensures the device's durability in harsh industrial or rugged environments.
4. Supply Voltage Range: The IC accepts a wide supply voltage range of 3.0 V to 5.5 V, allowing compatibility with various power sources and making it suitable for a range of portable applications
