HT82V36
Application Circuits
The recommended circuit configuration for 1-channel CDS mode operation is shown below.
The recommended input coupling capacitor value is 0.1mF (see circuit operation section for more details).
A single ground plane is recommended for the HT82V36. 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 the rest of the HT82V36. The
loading of the digital outputs should be minimized, either by using short traces to the digital ASIC, or by using external
digital buffers. All 0.1mF decoupling capacitors should be located as close as possible to the HT82V36 pins.

Note:
For the SHA Mode, all of the above considerations also apply, except that the analog input signal is directly
connected to the HT82V36 without using a coupling capacitor. The OFFSET pin should be grounded if the in-
put to the HT82V36 is to be referenced to ground, or a dc offset voltage should be applied to the OFFSET pin in
situation where a coarse offset needs to be removed from the input.
