First, the user must not ignore the datasneet 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. Bode Plot Figure datzsheet Apply a V step function to the input. Testing and other quality control techniques are used to the extent TI deems necessary to support this warranty.

Input Bias Current Figure datasheey. If a line is indented then it is a continuation of the previous line and the two combined represent the entire Device Marking for that device. Device is in production to support existing customers, but TI does not recommend using this part in a new design. Page numbers for previous revisions may differ from page numbers in the current version.

Buyer acknowledges and agrees that any military or aerospace use of TI components which have not been so designated is solely at the Buyer’s risk, and that Buyer is solely responsible for compliance with all legal and regulatory requirements in connection with such use. These amplifiers will operate with the common-mode input voltage equal to the positive supply.

Buyer represents and agrees that it has all the necessary expertise to create and implement safeguards which anticipate dangerous consequences of failures, monitor failures and their consequences, lessen the likelihood of failures that might cause harm and take appropriate remedial actions.

Operating the part near the maximum power dissipation may cause the part to operate outside specified limits.

TA can be estimated by same considerations as previously but, because of the added — propagation delay in the feedback loop A2 the overshoot is not negligible. A feedback pole is created when the feedback around any amplifier is resistive.

This component has a RoHS exemption for either 1 lead-based flip-chip solder bumps used between the die and package, or 2 lead-based die adhesive used between the die and leadframe. When one wishes to take advantage of the low input bias current of the LFx5x, typically less than 30 pA, it is essential to have an excellent layout. Where designed to be soldered at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.

The value of the added capacitor should be such that the RC time constant of this capacitor and the resistance it parallels is greater than or equal to the original feedback pole time constant. 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.

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.

This glossary lists and explains terms, acronyms, and definitions. However, if the feedback pole is less than approximately six times the expected 3-dB frequency a lead capacitor should be placed from the output to the input of the op amp.


In some cases, TI components may be promoted specifically to facilitate safety-related applications. Exceeding the negative common-mode limit on both inputs will force the amplifier output to a high state. The leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates. The information provided on this page represents TI’s knowledge and belief as of the date that it is provided.

Settling Time Test Circuit 8. 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. These devices can replace expensive hybrid and module FET operational amplifiers.

TI is not responsible or liable for any such statements. In normal operation the junction datzsheet rises above the ambient temperature as a result of internal power dissipation, Pd.

In fact, the common-mode voltage can exceed the positive supply by approximately mV independent of supply voltage and datwsheet the full operating temperature range. Open-Loop Voltage Gain Figure TI and TI suppliers consider certain information to be proprietary, and thus CAS numbers and other limited information may not be available for release.

This is to assure that salts and skin oils do not cause leakage paths on the surface of the package. This data is subject to change without notice and revision of this document.
