Product Summary
The EL6281CU is a combination read + 3 write level laser driver with IV amplifier. A dual amplitude, dual frequency RF oscillator sums on the output for laser noise reduction during read or write. All these functions are provided in 24-lead QSOP and LPP packages. The ENABLE pin enables the read & write channels. Positive current supplied to the IIN lines, through user selected resistors, allow the full scale range of each amplifier to be matched to the full scale range of the users control DACs. The applications of the EL6281CU include CD-RW to 16X, CD-R to 32X, Writable Optical Disk Drives.
