ATR0881
Overview
The ATR0881 is a laser diode driver designed to operate two grounded red laser diodes for CD and DVD and one floating blue laser diode for Blu-ray. The floating blue laser diode needs an extra supply voltage VH.
- Two High-side Outputs for Grounded Red Laser Diodes
- Total Output Current up to 700 mA at VLD = 3.8V
- One Low-side Output for Floating Blue Laser Diode
- Total Output Current up to 550 mA, External LD Supply Voltage
- Five Channels with Gain DACs
- Two Current Inputs for Read and Write Channels
- Channel 2 Current Contribution up to 350 mA
- LVDS-compatible Enable Inputs at Channels 2, 3, 4 and HFM
- Optional SyncDrive Technology for Increased Timing Accuracy
- Common Enable Input for All Channels
