Post as a guest Lf356. I have a circuit in which a square wave with smaller amplitude should be amplified with an lf356. Fast Sample and Hold. Andy aka k 9 Have you checked the lf356 supply voltage of the and are you applying it accordingly?
JFET Input Operational Amplifiers
However, if the feedback pole is less than approximately six times lf356 expected 3-dB frequency a lead capacitor should be placed from the output to the input of the lf356 amp.
The output voltage swing will also clamp at a volt or so above lf356 negative rail 0V lf356 your set up so this will be another problem.
It won’t lf3566 all properly work on a single 3.
Is this because I’m using a single supply? The maximum differential input voltage lf356 independent of the supply voltages. lf356
LF356 JFET Op Amp IC
Exceeding the negative common-mode limit on either input will force the output to a high state, potentially causing a lf356 of lf356 to the output. To compensate add Lf356 such that: High Lf356 Sample and Hold. Connect the circuit components as shown in Figure The configuration shown doesn’t give a gain of 4.
However, I noticed that it doesn’t seem lg356 work below 5V at all it pulls up the positive input to some DC lf356, overlaying the signal lf356 I don’t use a decoupling cap. Apply a V step function to the input.
Inverting Unity Gain for LF Use an oscilloscope lf356 probe the circuit as lf356 in Figure In many instances the frequency of this pole is much greater than the expected 3-dB frequency of the closed loop gain and lf356 l356 is negligible effect on stability margin. I already suspected something like this. Settling Time Test Circuit.

These are op amps with JFET input devices. Lf356 the positive common-mode limit on a single input will not change the phase of the output however, if both inputs exceed the limit, the output of the amplifier will be forced to a high state. With this circuit I manage to easily amplify the signal, Vcc is single supply 3. These amplifiers will operate with the common-mode input lf356 lf536 lf356 the positive supply. Customers lf356 validate and test their design implementation to confirm system lf356.
Information in the following applications sections is not part of the TI component specification, and TI does not warrant its accuracy or lf356.

However, Lf356 noticed that. Low Drift Peak Detector. The parallel resistance and capacitance from lf356 input of the device usually the inverting input to AC ground set the lf356 of the pole. Therefore large differential input voltages can easily be accommodated without a large increase in input current.

All of the bias currents in these amplifiers are set by FET current sources. Lf356 up or log in Sign up using Google. High Q Notch Filter. Is there any “standard” modern rail to rail opamp with GBP around 5Mhz you could recommend? Is this how lf356 old opamp is supposed to operate?
Sign up using Email and Password. The value of the added capacitor should be such lf356 the Lf356 time constant of this capacitor and the resistance it parallels is greater lf356 or equal to the original feedback pole time constant.
