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 oper-
ating 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 compo-
nents: photodiode, infrared LED, and current-setting
resistor. Optical components are external to allow maxi-
mum flexibility in PC board design. The MAX3120 is
available in 8-pin µMAX and SO packages. The µMAX
package consumes half the board space of an 8-pin
SO.
