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 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 – datasheet pdf

datasheey The simplified schematics of the IC is shown below:. The simplified schematics l,311 the IC is shown below: Documents Flashcards Grammar checker.

You can note that the Output voltage stays high when pin 2 has higher voltage than pin 7 and vice versa. Offset voltage null capability. Leakage Current vs Temperature Figure 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.

Review of LR circuits. You datashwet refer the other possible circuits from the LM datasheet given at bottom.

Supply Current vs Temperature Figure 9.

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. Supply Current vs Supply Voltage Figure Current Saturation Voltage Figure Normally these pins are not used since the Input Offset itself is much better controlled.

Input Bias Current vs Temperature Figure 2. 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.

National Semiconductor

A sample circuit is shown below in which the Inverting Terminal is set to 2. Common Mode Limits vs Temperature Figure 6. The LM can work on a Single supply voltage or in a dual supply mode.

Offset Voltage vs Input Resistance Figure 4. Input Bias Current vs Differential input voltage Figure 5.

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

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. The response time specified is for a mV input step with 5mV over drive. TL — Programmable Reference Voltage. Lab 9 in this note. 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 the user.
