1. Description
ATR0885 is a laser diode driver designed to operate three different grounded or float-
ing laser diodes for reading CDs (λ = 780 nm), DVDs (λ = 650 nm), and
HD-DVDs/Blu-ray (λ = 405 nm). An on-chip, low-EMI RF oscillator is available to
reduce laser mode hopping noise. The oscillator’s current amplitude can be set inde-
pendently for the three selectable outputs using three resistors (RSA, RSB, RSC).
The frequency setting is common to all IOUT outputs via a single resistor (RF). A logic
high level on the ENOSC pin enables the spread-spectrum RF oscillator. The
ATR0885 also includes a fast-settling transimpedance amplifier. It is provided to inter-
face between the front-end monitor photo diode and the adaptive laser diode power
control circuit. The gain of the transimpedance amplifier can set independently for
each of the three outputs using the resistors RTIA, RTIB and RTIC.

3. Absolute Maximum Ratings
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress rating
only and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of this
specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
