The SP8043 is a ten-channel photo detector IC (PDIC) designed for DVD and CD applications and can operate at wavelength of 650 and 780 nm. The device contains three photo diode (sensor) arrays, one of them with four identical sensors A D and others with two sensors (E, F and G, H respectively). The ten channels consist of four high speed channels (A, B, C, and D), four slow channels (E, F, G, and H), and two RF channel with paraphase output (RF+ and RF-). The high speed channel output provides a signal from one of the sensors A D. The E, F, G, and H channels output is used for servo control. The RF channels output is the sum of A + B + C + D channels with identical weights given to all channels.

Two gain select inputs allow the setting of four gain modes and a Power Down mode with low power consumption if Gain 2 input left floating.

The SP8043 is manufactured with an advanced 10GHz BICMOS technology.
