Description: 16-BIT CONSTANT CURRENT LED SINK DRIVER

Features

* 16 constant-current output channels
* Constant output current invariant to load voltage change Constant output current range: 3~45mA @ VDD=5V 3~30mA @ VDD=3.3V
* Excellent output current accuracy: between channels: ±2.5% (max. ), between ICs: ±3.0% (max. )
* Output current adjusted

Applications

* e. g. LED panels. Users may adjust the output current from 3mA to 45mA through an external resistor, Rext, which gives users flexibility in controlling the light intensity of LEDs. UTC L16B45A guarantees to endure maximum 17V at the output port. The high clock frequency, 25MHz, also satisfies the sy
