Note 1:
Absolute Maximum Ratings indicate limits beyond which damage to the device may occur.
Note 2:
Operating ratings indicate conditions for which the device is functional, but do not guarantee specific performance limits. For guaranteed specifications and
test conditions, see the Electrical Characteristics. Datasheet min/max specification limits are guaranteed by design, test, or statistical analysis. The guaranteed
specifications apply only for the test conditions listed. Some performance characteristics may change when the device is not operated under the listed test
conditions.
Note 3:
All voltages are measured with respect to GND, unless otherwise specified.
Note 4:
Calculated value from Voltage Gain test on each channel.
Note 5:
Linearity Error is the variation in DC gain from V

= 1.10V to V

Note 7:
Running the 1 MHz to 30 MHz test pattern at 1080i this part will dissipate approximately 15.2 W. This is the commonly accepted test pattern that is
representative of the worst case high frequency content for normal television viewing. This is the pattern used to estimate the worst case power dissipation of the
LM2452 in its normal application. It is recommended to use a heat sink with a thermal resistance under 3C/W.
