Figure 2 shows the test circuit used for evaluation of the LM Clamp Amplifier.

80V Triple Bias Clamp

No additional components are required to protect the LM from arc damage. Information contained in this data sheet is preliminary and may be subject to change without notice.

Capacitor C4 stabilizes the entire node at the anode of the clamp diode, D3, by creating a low impedance at high frequencies. 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. All voltages are measured with respect to GND, unless otherwise specified. 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.


The DC transfer function is shown in Figure 4. The output requires pull-up resistor to 80V. Absolute Maximum Ratings indicate limits beyond which damage to the device may occur.

The guaranteed specifications apply only for the test conditions listed. To obtain lm480 boards contact the National Semiconductor Sales Office in your region. Simplified Schematic One Channel?

F capacitor should be connected from the supply pin, Vcc, to ground, as close to the supply and ground pins as is practical. The DC clamp circuit amplifies the input signal by and the gain is set by the resistor ratio of 18R and R.

Each amplifier has its gain internally set to Some performance characteristics may change when the device is not operated under the listed test conditions. Operating Ratings indicate conditions for which the device is functional, but do not guarantee specific performance limits.
