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.

An Emitter Output Circuit is shown below. Saturation voltage vs Current Figure 8.

LM311 datasheet

If the voltage at the Non-Inverting Terminal pin 2 is higher than the Inverting Terminal dtaasheet 2the output pin 7 will also be high else the output will be low. Supply Current vs Temperature Figure 9. TL — Programmable Reference Voltage. You can note that the Output voltage stays high when pin 2 has higher voltage than pin 7 and vice versa. Supply Current vs Supply Voltage Figure Leakage Current vs Temperature Figure Review of LR circuits. 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.


National Semiconductor

Input Bias Current vs Temperature Figure 2. Input Bias Current vs Differential input voltage Figure 5. Documents Flashcards Grammar checker. The pins 5 and 6 on the Op-amp are used to set the balance voltage if you want to manually adjust the DC-Offset voltage.

Normally these pins are not used since the Input Offset itself is much better controlled. Submitted by admin on 6 March Input Offset Current vs Temperature Figure 3. The response time specified is for a mV input step with 5mV over drive.

LM Pinout, Pin Configuration, Specifications, Equivalent, Working & Datasheet

The simplified schematics of the IC is shown below:. A critical component in any component of a life support device or system whose failure to perform can be reasonably eatasheet to cause the failure of the life support device or system, or to affect its safety or effectiveness. The simplified schematics of the IC is shown below: When not in use the pins 5 and 6 should be shorted as shown above.

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. Common Mode Limits vs Temperature Lm311 6. Offset Voltage vs Input Resistance Figure 4.


A sample circuit is datashet below in which the Inverting Terminal is set to 2. The device is also designed to operate from dual or single supply voltage. 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 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 of datadheet user.

Offset voltage null capability.

Lab 9 in this note. Current Saturation Voltage Figure The LM datashet work on a Single supply voltage or in a dual supply mode. You can refer the other possible circuits from the LM datasheet given at bottom. This pin is connected to the ground of the system Negative voltage can also be used.

Low input bias current:
