Overall system slower than fast sample and hold R1, CC: Samples may or may not be available.

Due to limited production test time, the input bias currents measured are correlated to junction temperature. Use of a heat sink is recommended if input bias current is to be kept to a minimum. Apply a V step function to the input.

Fortunately, the techniques of obtaining low leakages are quite simple. When one wishes to take advantage of the low input bias current of datasheeet LFx5x, typically less than 30 pA, it is essential to have an excellent layout. 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. Maximum power dissipation is defined by the package characteristics.

Input Bias Current Figure 3. As with most amplifiers, care should be taken with lead dress, component placement and supply decoupling in order to ensure stability.

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 devices can replace expensive hybrid and module FET operational amplifiers. Buyers should obtain the latest relevant information before placing orders and should verify that such information is current and complete.

Pin Configuration and Functions Created to foster collaboration among engineers. Lab 9 in this note. The parallel resistance and capacitance from the input of the device usually the inverting input to AC ground set the frequency of the pole. 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. TI is not responsible or liable for any such statements.

Categories include technical documents, support and community resources, tools and software, and quick access to sample or buy. Where designed to be soldered at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.

Negative Current Limit Figure 8. 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. This information is the most current data available for the designated devices.

Equivalent Input Noise Voltage Figure Use of such information may require a license from a third party under the patents or other intellectual property of the third party, or a license from TI under the patents or other intellectual property of TI.


The Temperature Coefficient of the adjusted input offset voltage changes only a small amount 0. Normalized Slew Rate Figure Documents Flashcards Grammar checker.

Do not insert the input pin of the amplifier into the board at all, but bend it up in the air and use only air as an insulator. Output Impedance Figure For example, resistors from the output to an input should be placed with the body close to the input to minimize pick-up and maximize the frequency of the feedback pole by minimizing the capacitance from the input to ground.

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. Very popular in portable systems with low.
