ATR1842-P1QW 1. Description

The ATR1842 is a front monitor diode (FMD) which controls the laser power of theoptical pickup for Blu-ray/HD-DVD, DVD and CD drives in one IC.With the serial programming interface (SPI) it is possible to fit the laser power forBlu-ray/HD-DVD, DVD and CD. 2 bits are used to set the mode/gain level and 6 addi-tional bits are used for gain trimming, within ±6 dB. Also setting into sleep mode canbe done via the serial programmin interface (SPI).The integrated PIN diode and the high speed amplifier with low output impedanceensures stable driver performance.All output channels are set to tri-state during sleep mode.Due to its small package size the ATR1842 is especially suited for applications withlow height requirements like SLIM and Ultra-SLIM drives.

ATR1842-P1QW Applications


• Blu-ray/HD-DVD
• DVD+RW with CD-RW Capability
• DVD-RW with CD-RW Capability
• DVD-RAM with CD-RW Capability
• Recordable Optical Data Storage Devices
