Description

The U8600B is a monolithic integrated circuit using TEMIC's advanced UHF technology. The IC is a very high-speed, mixedsignal laser driver circuit for re-writable optical systems.

U8600B comprises a servo amplifier to drive the laser diode, a high-frequency modulator for noise reduction, power and pulse-width generators as well as several operation control and safety functions.
