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.

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

Review of LR circuits.

Leakage Current vs Temperature Figure Input Offset Current vs Temperature Figure 3. Lab 9 in this note. If the voltage at the Non-Inverting Terminal pin 2 is higher than the Daatsheet Terminal pin 2the output pin 7 will also be high else the output will be low.

Supply Current vs Temperature Figure 9. TL — Programmable Reference 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 dataasheet in a significant injury of the user.


Input Bias Current vs Temperature Figure 2.

Current Saturation Voltage Figure Supply Current vs Supply Voltage Figure Low input bias current: An Emitter Output Circuit is shown below. The response time specified is for a mV input step dqtasheet 5mV over drive. The LM can work on a Single supply voltage or in a dual supply mode.

The simplified schematics of the IC is shown below:.

datashert This pin is connected to the ground of the system Negative voltage can also be used. When not in use the pins 5 and 6 should be shorted as shown above. Documents Flashcards Grammar checker. Saturation voltage vs Current Figure 8. A critical component in any component of datashfet 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.

Submitted by admin on 6 March 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.


You can refer the other possible circuits from the LM datasheet given at bottom. The device is also designed to operate from dual or single supply voltage. The pins 5 and 6 on the Op-amp are used om311 set the balance voltage if you want to manually adjust the DC-Offset voltage.

The simplified schematics of the IC is shown below: The transistor can also make the Load to be isolated from the system ground, so datasjeet you are looking for a Voltage comparator to drive loads of these specifications then this IC might be the right choice for you. Offset voltage null capability. You can note that the Output voltage stays high when pin 2 has higher voltage than pin 7 and vice versa.

Common Mode Limits vs Temperature Figure 6. A sample circuit is shown below in which the Inverting Terminal is set to 2. Normally these pins are not used since the Input Offset itself is much better controlled.
