Product Summary

The MAX3120ESA is an IrDA 1.2-compatible infrared transceiver. It is optimized for battery-powered, space-constrained applications. It consumes only 120μA while supporting data rates up to 115kbps over a wide 3V to 5.5V operating range, and features a 10nA shutdown mode to further extend battery life. The MAX3120ESA reduces the space required for IrDA applications by requiring a minimum of external components: photodiode, infrared LED, and current-setting resistor. The MAX3120ESA is designed for IrDA Applications, Personal Digital Assistants(PDAs), Palmtop Computers, Cell Phones, Hand-Held Equipment, Peripherals.
