control of CCD imager. The VSP2212 is the
high-performance version of the VSP2000/2100 fami-
lies. The VSP2212Y is available in an LQFP-48 pack-
age and the VSP2212M is avail able in a VQFN-48
package. Both products operate from a single +3V/
+3.3V supply.

This integrated circuit can be damaged by ESD. Burr-Brown
recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling
and installation procedures can cause damage.
ESD damage can range from subtle performance degrada-
tion to complete device failure. Precision integrated circuits
may be more susceptible to damage because very small
parametric changes could cause the device not to meet its
published specifications.

NOTES: (1) Type designators: P = Power Supply and Ground; DI = Digital Input; DO = Digital Output; AI = Analog Input; AO = Analog Output. (2) Refer to the “Serial
Interface” section for more detail. (3) Should be connected to ground with a bypass capacitor. We recommend the value of 0.1µF to 0.22
µF,
however, it depends
on the application environment. Refer to the “Optical Black Level Clamp Loop” section for more detail. (4) Should be connected to ground with a bypass capacitor.
We recommend the value of 1000pF, however, it depends on the application environment. Refer to the “Voltage Reference” section for more detail. (5) Should be
connected to ground with a bypass capacitor (0.1µF). Refer to the “Voltage Reference” section for more detail.
