XRD9815 System Offset
January 2000-4
The XRD9815 is connected as shown below to test for system offset. All input pins and VCOM
pin are bypassed to AGND through capacitors such that only system offset within the
XRD9815 is measured. In the circuit below, 0.01
μ
F capacitors are used to connect input pins
and 0.03
μ
F capacitor is used to connect the VCOM pin.

Figure 1. XRD9815 Application Circuit for Measuring
System Offset in 3 Channel, CCD Mode
Bench data showed a linear relationship between the system offset of XRD9815 and PGA
gain. A system offset vs. gain plot for all three channels is shown in Figure 2 below.
