XRD9827 10 Rev. 1.20 RL VRT VRB VDD RED XRD9827 DC REFERENCE C I S M U X N/C N/C VDCEXT The DC reference voltage applied to VDCEXT does not have to be accurate. The internal offset DAC voltage is still used in this mode for fine adjustment. VDCEXT cannot be used as an input from the CIS. Any signal applied to VDCEXT will be subtracted from the output signal of the multiplexer. Figure 4. Application with Offset Greater Than (-100mv to 500mv) |
