LM311 DATASHEET PDF

LM is an excellent Operational amplifier capable of driving DTL, RTL, TTL, or MOS logic. The output can switch voltages to 50 volts at currents to description/ordering information. The LM, LM, and LM are single high -speed voltage comparators. These devices are designed to operate from a. The LM LM and LM are voltage comparators that have input currents nearly a thousand times lower than devices like the LM or LM They are.

The simplified schematics of the IC is shown below: Input Offset Current vs Temperature Figure 3. Normally these pins are not used since the Input Offset itself is much better controlled.

You can note that the Output voltage stays high when pin 2 has higher voltage than pin 7 and vice versa. Input Bias Current vs Differential input voltage Figure 5.

Lab 9 in this note. You can refer the other possible circuits from the LM datasheet given at bottom. Current Saturation Voltage Figure The pins 5 and 6 on the Op-amp datassheet used to set the balance voltage if you want to manually adjust the DC-Offset voltage. An Emitter Output Circuit is shown below. The device is also designed to operate from dual or single supply voltage. Offset voltage null capability. The simplified schematics of the IC is shown below:.

This pin is connected to the datashedt of the system Negative voltage can also be used. A critical component in 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. Review of LR circuits.

lm31 When not in use the pins 5 and 6 should be shorted as shown above. Leakage Current vs Temperature Figure Documents Flashcards Grammar checker. Input Bias Current vs Temperature Figure 2.

Supply Datashet vs Supply Voltage Figure Supply Current vs Temperature Figure 9. A sample circuit is shown below in which the Inverting Terminal is set to 2. The transistor can also make the Load to be isolated from the system ground, so if you are looking for a Voltage comparator to drive loads of these specifications then this IC might be the right choice for you.

Any Op-Amp can be made to work as a voltage comparator, but the LM proves itself to be advantages by housing an Output Transistor inside its package. If the voltage at the Non-Inverting Terminal pin 2 is higher than the Inverting Terminal pin 2the output pin 7 will also be high else the output will be low.

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 c whose failure datsaheet perform when properly used in accordance with instructions for use datashheet in the labeling, can be reasonably expected to result in a significant injury of the user.

Offset Voltage vs Input Resistance Figure 4. The response time specified is for a mV input step with 5mV over drive.
