The DC transfer function is shown in Figure 4.

Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Application Circuit The application circuit shown in Figure 5 is designed to help clamp the voltage at the output of the driver to the desired level. For guaranteed specifications and the test conditions, see the Electrical Characteristics.

Each amplifier has its gain internally set to A critical component is any component of a life support device or system whose failure to perform can be reasonably expected to cause the failure of the life support device or system, or to affect its safety or effectiveness.


Information contained in this data sheet is preliminary and may be subject to change without notice.

It shows all the components necessary to optimize performance as well as to protect against damage from a CRT arc event. Operating Ratings indicate conditions for which the device is functional, but do not guarantee specific performance limits.

Figure 2 shows the test circuit used for evaluation of the LM Clamp Amplifier. The DC clamp circuit amplifies the input signal by and the gain is set by the resistor ratio of 18R and R. Life support devices or systems are devices or systems which, a are intended for surgical implant into the body, or b support or sustain life, and whose failure to perform when properly used in accordance with instructions for use provided in the labeling, can be reasonably expected to result in a significant injury to the user.

Some performance characteristics may change when the device is not operated under the listed test conditions. The guaranteed specifications apply only for the test conditions listed. All voltages are measured with respect to GND, unless otherwise specified. Capacitor C4 stabilizes the entire node at the anode of the clamp diode, D3, by creating a low impedance at high frequencies.

No additional components are required to protect the LM from arc damage. National Semiconductor Corporation Americas Email: F capacitor should be connected from the supply pin, Vcc, to ground, as close to the supply and ground pins as is practical.

To obtain demonstration boards contact the National Semiconductor Sales Office in your region. The output requires pull-up resistor to 80V.
