Distributors for availability and specifications. Rating to be determined. Average TC of Input. Equivalent Input Noise Voltage. Equivalent Input Noise Current. Operating Ratings indicate conditions for which the device ,f411. Unless otherwise specified the absolute maximum negative input voltage is equal to the negative power supply voltage. These devices are available in both the commercial temperature range 0?


C and the military temperature range ? A “C” indicates the commercial temperature range and lf41 “M”.

The military temperature range is available in “H” package only. The input bias currents are junction leakage currents which approximately double for every 10? C increase in the junction temperature, T j. In normal operation the junction temperature rises above the ambient. Use of a heat sink is. Supply voltage rejection ratio is measured for both supply magnitudes increasing or decreasing simultaneously in accordance with common practice, from.

Power Dissipation is defined by the package characteristics. Operating the part near the Max. Power Dissipation may cause the part to operate.

Open Loop Voltage Gain. Datasneet LF is biased by a zener reference which allows. If the amplifier is forced to drive. Therefore, large differential input voltages can easily be. However, neither of the input voltages.

Precautions should be taken to ensure that the power supply. Datashewt the negative common-mode limit on either input. As with most amplifiers, care should be taken with lead. In neither case does a latch occur. For example, resistors from the output to. Exceeding the positive common-mode limit on a single input.


A feedback pole is created when the feedback around any. The parallel resistance and capacitance.
