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.

Lab 9 in this note. A critical component in any datashee 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 device is also designed to operate from dual or single supply voltage.

Documents Flashcards Grammar checker. 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.

The simplified schematics of the IC is shown below:.


National Semiconductor – datasheet pdf

The pins 5 and 6 on the Op-amp are dqtasheet to set the balance voltage if you want to manually adjust the DC-Offset voltage. Saturation voltage vs Current Figure 8. An Emitter Output Circuit is shown below. The simplified schematics of the IC is shown below: Input Bias Current vs Differential input voltage Figure 5.

lm11 Submitted by admin on 6 March 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.

The LM can work on a Single supply voltage or in a dual supply mode.

LM311 datasheet

Low input bias current: This pin is connected to the ground of the system Negative voltage can also be used. Common Mode Limits vs Temperature Figure 6.

Input Bias Current vs Temperature Figure 2. You can refer the other possible circuits from the LM datasheet given at bottom.

Offset voltage null capability. Input Offset Current vs Temperature Figure 3. Review of LR circuits. 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.


When not in use the pins 5 and 6 should datawheet shorted as shown above. Normally these pins are not used since the Input Offset itself is much better controlled.

TL — Programmable Reference Voltage. Supply Current vs Supply Voltage Figure Leakage Current vs Temperature Figure 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.

Current Saturation Voltage Figure You can note that the Output voltage stays high datasheeh pin 2 has higher voltage than pin 7 and vice versa. A sample circuit is shown below in which the Inverting Terminal is set to 2. The response time specified is for a mV input step with 5mV over drive. Offset Voltage vs Input Resistance Figure 4.
