Description
Atmel’s AT78C1505 contains the necessary preamplifiers for DVD or CD front-end
read electronics. The AT78C1505 is a DVD/CD preamp responsible for amplification
of slow/fast photodetector signals for CD-ROM, DVD-ROM or DVD-RAM data. The
preamp also includes an additional single-ended transimpedance amplifier with
programmable gain and offset adjustment which can be used for laser power monitor.
The CMOS preamplifier operates from a single 3.3V supply and is fully programmable
through a serial interface for either CD or DVD modes.
