Supply Voltage (V CC) +250V Bias Voltage (V BB) +16V Input Voltage (V IN) −0.5V to V BB +0.5V Storage Temperature Range (T STG) −65˚C to +150˚C Lead Temperature (Soldering, <10 sec.) 300˚C ESD Tolerance, Human Body Model 2 kV Machine Model 200V Junction Temperature 150˚C θ JC (typ) 4.0˚C/W Operating Ratings (Note 2) V CC +100V to +230V V BB +7V to +13V V IN +0V to +5V V OUT +40V to +215V Case Temperature (10W max power) 110˚C Do not operate the part without a heat sink and thermal grease. Heat sink must have a thermal resistance under 5.0˚C/W. (Note 7) Electrical Characteristics (See Figure 3 for Test Circuit). Unless otherwise noted: V CC = +220V, VBB = +12V, VDAC = +0.5V, CL = 10 pF, TC = 50˚C. DC Tests: V IN = +2.7VDC. AC Tests: Output = 130VPP (60V – 190V) at 1 MHz.

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 VIN = 1.10V to VIN = 4.30V. Note 6: Input from signal generator: tr,tf < 10 ns. Note 7: Running the 1 MHz to 30 MHz test pattern at 1080i this part will dissipate approximately 10 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 LM2451 in its normal application. It is recommended to use a heat sink with a thermal resistance of 5.0˚C/W or better. www.national.com 2 |
