DESCRIPTION

The SP8040 is a high performance 4 channel PDIC with a fully integrated photo detector array

ideally suited for high speed DVDRW, DVDRAM and CDRW systems that incorporate separate

paths for CD and DVD information. Responsivity is fully specified at 650nm. There are 4 high

speed channels (A, B, C, D) for data detection and an additional output, V

sum of the high speed channels.

The SP8040 is manufactured with an advanced, CMOS process that enables integration of on-

board multiple photo detector arrays.
