Features, Applications The LM series are precision high speed dual comparators fabricated on a single monolithic chip.
They are designed to operate over a wide range of supply voltages down to a single 5V logic supply and ground. Further, they have higher gain and lower input currents than devices like the LM The LMA offers improved precision over the standard LM, with tighter tolerances on offset voltage, offset current, and voltage gain.
Although designed primarily for applications requiring operation from digital logic supplies, the LM series are fully specified for power supplies 15V.
It features faster response than the LM at the expense of higher power dissipation. However, the high speed, wide operating voltage range and low package count make the LM much more versatile than older devices like the LM Do not operate the device with more than 16V from ground to VS. Note 6: The offset voltages and offset currents given are the maximum values required to drive the output within a volt of either supply with 1 mA load.
Thus, these parameters define an error band and take into account the worst case effects of voltage gain and input impedance. Note 7: The response time specified see definitions is for mV input step with 5 mV overdrive.
Note 8: Output is pulled to 15V through 1. Note The offset voltages and offset currents given are the maximum values required to drive the output within a volt of either supply with 1 mA load. Note The response time specified is for mV input step with 5 mV overdrive.
Note Output is pulled to 15V through 1.
