LD1016
16 CHANNEL CONSTANT CURRENT LED DRIVERS
DESCRIPTION
The LD1016(LD71D0016) is specifically designed for LED display. LD1016 contains a serial buffer
and data latches which convert serial input data to parallel output format. At LD1016 output stage,
sixteen regulated current ports are designed to provide uniform and constant current for driving
LED within a large range of V
DS
variations.
Users may adjust the output current from 5mA to 90mA through an external resistor, R
EXT
which
gives users flexibility in controlling the light intensity of LED. The high clock frequency, 25MHz, also
satisfies the high speed system requirements.
