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
Note 3: All voltages are measured with respect to GND, unless otherwise specified.
Note 4: Linearity Error is the variation in DC gain from VIN = 1.15V to VIN = 4.35V.
Note 5: Input from signal generator: tr, tf < 2 ns. Slower inputs to the LM2432 will change the transient response characteristics and reduce power dissipation.
Note 6: IKERROR = IK – IOUT, where IK is the IK current output from pin 5 (IK) and IOUT is the cathode current into pin 2 (VOUT). IK is calculated by measuring VIK
across a known resistor value between pin 5 and GND.
Note 7: Refer to the RGB Video Processor data sheet for IK leakage compensation, feedback operation, and adjustment range information.
