MAX3120ESA+

The MAX3120ESA+ is a low-profile, 3V, 120μA, IrDA infrared transceiver in 8 pin NSOIC package. The MAX3120 IrDA 1.2 compatible infrared transceiver 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 MAX3120 reduces the space required for IrDA applications by requiring a minimum of external components such as photodiode, infrared LED and current-setting resistor. Optical components are external to allow maximum flexibility in PC board design. Typical applications include IrDA applications, personal digital assistants (PDAs), palmtop computers, cell phones, hand-held equipment and peripherals.

• Supply voltage range is 3V to 5.5V
• Operating temperature range from -40°C to 85°C
• High-current infrared LED drive is 200mA
• Flexible optics selection and layout
