Description

The TFDT4000 is an infrared transceiver for data communication systems. The transceiver is compatible to the IRDA standard and allows data rates up to 115 kbit/sAn internal AGC (Automatic Gain Control) ensures proper operation under EMI conditions.
 
The internal IRED driver can be connected by the external current control resistor to an independent unregulated power supply. This will add more freedom in circuit design and efficient serial drive capability for external IREDs for high power applications.
