ATR0885 Datasheet 3-output Laser Driver

Manufacturer: Atmel (now Microchip Technology)

Overview: ..

General Description

ATR0885 is a laser diode driver designed to operate three different grounded or floating laser diodes fo r reading CDs ( λ = 780 nm), DVDs ( λ = 65 0 n m) , a nd 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 independently for the three selectable outputs using three resistors (RSA, RSB, RSC).

Key Features

  • Three Selectable Outputs All Outputs Can Be Used Either for Standard (5V) or High Voltage (9V) Maximum Output Current at All Outputs Up to 150 mA On-chip Low-EMI RF Oscillator With Spread-spectrum Technology Control of 3 Different Swings Using 3 External Resistors Oscillator Frequency Range from 200 MHz to 500 MHz Maximum Oscillator Current Amplitude 100 mApp On-chip High-gain Transimpedance (IV) Amplifier.
