DESCRIPTION
In applications, an external resistor is used to set the full scale constant output current from 5mA up to 45mA. The output enable function gates all 8 outputs on and off, and is fast enough to be used as PWM input for LED intensity control. Since the serial data input rate can be reached up to 25MHz, the SCT2167 will satisfy system which needs high volume data transmission to control the LED FEATURES
8 constant current sinkers with output voltage sustainable to 17V Constant output current : 5 – 30/45mA@3.3/5V Excellent regulation to load, supply voltage and temperature Temperature regulation: ±0.005%/°C load regulation: ±0.1%/V line regulation: ±0.5%/V High current matching accuracy: ±1% between outputs, ±2% between ICs Fine grayscale response with 180ns PWM pulse width Dropout voltage 0.5V@20mA, VDD=5V CMOS Schmitt trigger inputs with clock rate up to 25MHz @ cascade connection The constant current value of 8 outputs is set by a single external resistor Interlaced 30ns de...
