MAXIM Integrated Products, represented in Australia by Arrow Electronics , has released the MAX3701 2X blue laser driver with integrated sample and hold.
A programmable, five-level output and up to 200mA of total output current allow this device to achieve a 0.9ns edge speed with an 8% overshoot. To monitor the optical-output power, this driver integrates a gain-selectable sample and hold circuit.
Also integrated is a programmable RF frequency and amplitude control with a range of 200Mhz to 600Mhz and 15mAp-p to 150mAp-p. The MAX3701 does not require any active external components to manage the voltage drop across a blue laser.
The MAX3701 is ideal for all blue laser applications, including high-density optical disc and industrial applications. It is available in a 5mm x 5mm 32-pin QFN package and operates in the 0°C-70°C temperature range.
