Application Circuits
The recommended circuit configuration for the 3-channel CDS mode operation is shown in the figure below. The rec-
ommended input coupling capacitor value is 0.1 F.
Asingle ground plane is recommended for the HT82V26A. Aseparate power supply may be used for DRVDD, the digi-
tal driver supply, but this supply pin should still be decoupled to the same ground plane as with the rest of the
HT82V26A.Theloadingofthedigitaloutputsshouldbeminimized,eitherbyusingshorttracestothedigitalASIC,orby
using external digital buffers. To minimize the effect of digital transients during major output code transitions, the falling
edge of the CDSCLK2 should occur in coincidence with or before the rising edge of ADCCLK. All 0.1 F decoupling ca-
pacitors should be located as close as possible to the HT82V26A pins. When operating in a single channel mode, the
unused analog inputs should be grounded.
Note:
For the 3-channel SHAmode, all of the above considerations also apply for this configuration, except that the
analog input signals are directly connected to the HT82V26Awithout the use of coupling capacitors. The OFF-
SET pin should be grounded if the inputs to the HT82V26Aare to be referenced to ground, or a DC offset volt-
age should be applied to the OFFSET pin in the case where a coarse offset needs to be removed from the
inputs. The analog input signals must already be dc-biased between 0V and 2V, if OFFSET is connected to
ground.
