Operating Conditions
Table 2.
DC Characteristics
Notes:
1. Ground: note that the package metal back is grounded.
2. In dynamic mode, to avoid possible damage to the device, the addition of a Schottky diode is recommended (for example;
diode reference BAR 43S) between VS1 and VSS ground in order to increase the potential on VS1, thus avoiding any direct
mode diode current during clock transitions.
Readout Mode
The serial readout register is operated in a two-phase transfer mode. However, there
are 6 separate command electrodes that should be connected differently, depending on
the required readout mode. The following table gives the connections to be made for
each mode.
