LN0134

16-bit constant current LED sink driver LN0134 ■ General Description LN0134 is designed for LED displays. As an enhancement of its predecessor, LN0134 exploits Precision Drive™ technology to enhance its output characteristics. LN0134 contains a serial buffer and data latches which convert serial input data into parallel output format. At LN0134 output stage, sixteen regulated current ports are designed to provide uniform and constant current sinks for driving LEDs within a large range of Vf variations. LN0134 provides users with great flexibility and device performance while using LN0134 in their system design for LED display applications, e.g. LED panels. Users may adjust the output current from 3 mA to 45 mA through an external resistor, Rext, which gives users flexibility in controlling the light intensity of LEDs. LN0134 guarantees to endure maximum 17V at the output port. The high clock frequency, 25 MHz, also satisfies the system requirements of high volume data transmissio...
