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. Lab 9 in this note. 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. Saturation voltage vs Current Figure 8.
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. The simplified schematics of the IC is shown below: The LM can work on a Single supply voltage or in a dual supply mode. Review of LR circuits. Input Bias Current vs Temperature Figure 2.
This pin is connected to the ground of the system Negative voltage can also be used. The device is also designed to operate from dual or single supply voltage. Leakage Current vs Temperature Figure Current Saturation Voltage Figure Low input bias current: Supply Current vs Supply Voltage Figure Common Mode Limits vs Temperature Figure 6.
The pins 5 and 6 on the Op-amp are used to set dagasheet balance voltage if you want to manually adjust the DC-Offset datashet. You can note that the Output voltage stays high when pin 2 has higher voltage than pin 7 and vice versa. You can refer the other possible circuits from the LM datasheet given at bottom. When not in use the pins 5 and 6 should be shorted as shown above. Input Bias Current vs Differential input voltage Figure 5.
Documents Flashcards Grammar checker. Submitted by admin on 6 March 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 datasheet.
Normally these pins are not used since the Input Offset itself is much better controlled.
A sample circuit is shown below in which the Inverting Terminal is set to 2. 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 response time specified is for a mV input step with 5mV over drive. Supply Current vs Temperature Figure 9. Offset voltage null capability. The simplified schematics of the IC is shown below:.

Life support datassheet 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 datasheeet used in accordance with instructions for use provided in the labeling, can be reasonably expected to result in a significant injury of the user.
TL — Programmable Reference Voltage. Input Offset Current vs Temperature Figure 3. Offset Voltage vs Input Resistance Figure 4.
