DATASHEET ISL58831 Dual Laser Driver with APC Amplifier and Spread Spectrum Oscillator FN7440 Rev 1.00 Jan 28, 2016 The ISL58831 is a combination read + 3 write level laser driver and IV amplifier, with an extra read + oscillator ROM channel for use in dual-laser ‘Combo’ drivers. A separate (amplitude and frequency) oscillator modulates the selected output for laser noise reduction during read or write. All these functions are provided in a 24 Ld QFN package. The SEL1 pin, when high, selects the DVD (write) laser. Positive current supplied to the IIN lines, through a user-selected resistor, allow the full-scale range of each amplifier to be matched to the full-scale range of the users control DACs.
