PGA280: PGA280 for CCD AFE

Part Number: PGA280
Other Parts Discussed in Thread: PGA870


I am new to analog circuit design and I need to design the analog front end for a CCD imaging system (Pushbroom camera). I am using the TCD2905 RGB linear CCD and the LTC2246 ADC. I need help in integrating the PGA280 in my system (design considerations and best practices). It is the best fit for my application as I need to digitally control the gain and set the output's common-mode voltage according to the ADC's requirements. The CCD operates at a maximum frequency of 20MHz but I am only planning on operating at 4MHz. Any help is greatly appreciated.I have attached the datasheets of the CCD sensor and the ADC.

Best Regards,
