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. The serial interface (SPI and TWI supported) makes ATR0881 very flexible and configurable for a wide range of applications.
