ATR0881 Datasheet (ATMEL) - 3-output Laser Driver

ATR0881, 3-output Laser Driver

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 configurabl
