Equivalent Input Noise Voltage Figure datashest TI is not responsible or liable for such altered documentation. When the LFx5x is manufactured, the device is always handled with conductive finger cots. Negative Current Limit Figure 8.

Bode Plot Figure For browser-based versions of this data sheet, refer to the left-hand navigation. Product device recommended for new designs. Information published by TI regarding third-party products or services does not constitute a license to use such products or services or a warranty or endorsement thereof. Overall system slower than fast sample and hold R1, CC: This information is the most current data available for the designated devices.

Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. Datashfet Bias Current Figure 4. This component has a RoHS exemption for either 1 lead-based flip-chip solder bumps used between datasheeh die and package, or 2 lead-based die adhesive used between the die and leadframe.

Air Wiring Another potential source of leakage that might be overlooked is the device package. The value of the added capacitor should be such that dtasheet RC time constant of this capacitor and the resistance it parallels is greater than or equal to the original feedback pole time constant. Device has been announced but is not in production. These amplifiers will operate with the common-mode input voltage equal to the positive supply.


Buyer will fully indemnify TI and its representatives against any damages arising out of the use of any TI components in safety-critical applications.

LF357 Datasheet

Created kf357 foster collaboration among engineers. Ratasheet compensate add C2 such that: Common-mode rejection and open-loop voltage gain are also unaffected by offset adjustment. TI is not responsible or liable for any such statements. Resale of TI components or services with statements different from or beyond the parameters stated by TI for that component lt357 service voids all express and any implied warranties for the associated TI component or service and is an unfair and deceptive business practice.

In this case you may have to forego some of the advantages of PCB construction, but the advantages are sometimes well worth the effort of using point-to-point up-in-the-air wiring. First, the user must not ignore the surface leakage of the PCB, even though it may sometimes appear acceptably low, because under conditions of high humidity or dust or contamination, the surface leakage will be appreciable.

LF Datasheet PDF ( Pinout ) – Series Monolithic JFET Input Operational Amplifiers

These amplifiers feature low input bias and offset currents, as well as low offset voltage and offset voltage drift, coupled with offset adjust which does not degrade drift or common-mode rejection. In no event shall TI’s liability arising out of such information exceed the total purchase price of the TI part s at issue in this document sold by TI to Customer on an annual basis. This PC foil must then be connected to a voltage that is at the same voltage as the amplifier inputs, because no leakage current can flow between two points at the same potential.


Fortunately, the techniques of obtaining low leakages are quite simple. No TI components are authorized for use in FDA Class III or similar life-critical medical equipment unless authorized officers of the parties have executed a special agreement specifically governing such use. This data is subject to change without notice and revision of this document. The maximum differential input voltage is independent of the supply voltages.

Therefore large differential input voltages can easily be accommodated without a large increase in input current. Typical Connections Of Guard Rings The designer should be aware that when it is inappropriate to lay out a PCB for the sake of just a few circuits, there is another technique which is even better than a guard ring on a PCB: Open-Loop Voltage Gain Figure TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.

These devices can replace expensive hybrid and module FET operational amplifiers. Leakage of D2 provided by feedback path through Rf.
