DESCRIPTION

The SP8050A is a high performance 8 channel PDIC with a fully integrated photo detector array ideally suited for high speed DVDRW, DVDRAM and CDRW systems. Responsivity is fully specified at wavelengths of 650nm and 780nm. The 8 channels consist of 4 high speed channels (A, B, C, D) for data detection as well as 4 tracking channels (E, F, G, H) for beam positioning requirements. Two additional outputs (RF+ and RF-) representing the sums of the high speed channels are also provided.

■ Settling Time: 8ns to 1 for 1.5V step

■ Three selectable Gain Settings

■ Group DelayError less than 2ns up to 70MHz

■ Low Offset Drift of less than 20µV/ °C

■ Low Offset Voltage of less than 10mV
