AD9660KR-REEL

Overview

The AD9660KR-REEL is a highly integrated laser diode driver designed for optical disk drives, printers, and copiers. It features onboard light power control loops that utilize feedback from an external photodetector to manage bias and write power levels. The device supports switching between power levels at up to 200 MHz. Key electrical parameters include output rise and fall times of typically 1.5 ns and 2.0 ns, respectively. It operates on a single +5 V power supply and delivers an output current of 180 mA at 3 V or 200 mA at 2.5 V. Bias current is specified at 90 mA at 3 V, with modulation and offset currents at 60 mA and 30 mA respectively.
