Features
16-Channel Constant Current LED Sink Driver with Low Knee Voltage
- 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: ±1.5% (typ.) and ±3% (max.) -between ICs: ±3% (typ.) and ±6% (max.)
- Low Knee Voltage: IOUT=20mA@VDS=0.2V; VDD=3.3V IOUT=20mA@VDS=0.2V; VDD=5.0V
- Output current adjusted through an external resistor
- Fast response of output current, OE (min.): 70ns with good uniformity between output channels
- Staggered delay of output
- 25MHz clock frequency
- Schmitt...
