EL6215 To request the full datasheet, please visit www.intersil.com/products/EL6215 Data Sheet June 15, 2004 FN7223 3-Channel Laser Diode Driver + Oscillator The EL6215 is a high-performance three channel laser driver that provides controlled current to a grounded laser diode. Write channels 2 and 3 should be used as the write channels, with switching speeds of approximately one nanosecond rise/fall time. All three channels are summed together at the IOUT output, allowing the user to create multilevel waveforms in order to optimize laser diode performance. The level of the output current is set by an analog voltage applied to an external resistor which converts the voltage into a current at the IIN pin (virtually ground).
