1. Tables show typical cross capacitance between pins of the device.
2. Capacitance is total for all like pins.
3. Capacitance values are estimated.
Device Identification
The device identification pin (DevID) may be used to determine which Truesense Imaging 7.4 micron pixel interline CCD
sensor is being used.

1. Nominal value subject to verification and/or change during release of preliminary specifications.
2. If the Device Identification is not used, it may be left disconnected.
3. After Device Identification resistance has been read during camera initialization, it is recommended that the circuit be disabled to prevent
localized heating of the sensor due to current flow through the R_DeviceID resistor.
Recommended Circuit
Note that V1 must be a different value than V2.
