... Applications Flatbed document scanners Film scanners General Description The HT82V26 is a complete analog signal processor for CCD imaging applications. It features a 3-channel archi- tecture designed to sample and condition the outputs of tri-linear color CCD arrays. Each channel consists of an input clamp, Correlated Double Sampler (CDS), offset DAC and Programmable Gain Amplifier (PGA), and a high performance 16-bit A/D converter ...

... CDS mode of operation, and setting this bit low will enable the SHA mode of operation. Bit D3 sets the dc bias level of the HT82V26¢s input clamp. This bit should always be set high for the 4V clamp bias, un- less a CCD with a reset feed through transient exceeding 2V is used. Setting the bit D3 low, the clamp voltage is 3V. Bit D2 controls the power-down mode. Setting bit D2 high will place the HT82V26 into a very low power ² ...

... The HT82V26 uses one Programmable Gain Amplifier (PGA) for each channel. Each PGA has a gain range from 1x (0dB) to 5.85x (15.3dB), adjustable in 64 steps. The Figure shows the PGA gain as a function of the PGA register code. ...

... A single ground plane is recommended for the HT82V26. A separate power supply may be used for DRVDD, the digital driver supply, but this supply pin should still be decoupled to the same ground plane as with the rest of the HT82V26. The loading of the digital outputs should be minimized, either by using short traces to the digital ASIC using exter- nal digital buffers ...
