The drain currents for the amplifiers are therefore essentially independent of supply voltage.

LF357N – LF357 JFET Input Op-Amp Datasheet

Buyers should obtain the latest relevant information before placing orders and should verify that such information is current and complete. Negative Current Limit Figure dqtasheet. Leakage of D2 provided by feedback path through Rf. All other pins connected to PCB.

The information provided on this page represents TI’s knowledge and belief as of the date that it is provided. Therefore large differential input voltages can easily be accommodated without a large increase in input current. In many instances the frequency of this pole is much greater than the expected 3-dB frequency of the closed loop gain and consequently there is negligible effect on stability margin.

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

Positive Current Limit Figure 9. Air is an excellent insulator. Buyer acknowledges and agrees dataxheet 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.


Important Information and Disclaimer: These devices can replace expensive hybrid and module FET operational amplifiers.

Lab 9 in this note. These JFETs have large reverse breakdown voltages from gate to source and drain eliminating the need for clamps across the inputs. However, neither of the input voltages should be allowed to exceed the negative supply as this will cause large currents to flow which can result in a datadheet unit.

TI bases its knowledge and belief on information provided by third parties, and makes no representation or warranty as to the dxtasheet of such information.

When the LFx5x is manufactured, the device is always handled with conductive finger cots. This is to dqtasheet that salts and skin oils do not cause leakage paths on the surface of the package. Where designed to be soldered at high temperatures, Lr357 Pb-Free products are suitable for use in specified lead-free processes. Voltage Swing Figure 5. Buyer will fully indemnify TI and its representatives against any damages arising out of the use of any TI components in safety-critical applications.


Wide Bandwidth Single J-fet Operational Amplifiers

Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. When one wishes to take advantage of the low input bias current of the LFx5x, typically less than 30 pA, datqsheet is essential to have an excellent layout.

Reproduction datashfet significant portions of TI information in TI data books or data sheets is permissible only if reproduction is without alteration and is accompanied by all associated warranties, conditions, limitations, and notices.

The maximum differential input voltage is independent of the supply voltages. This data is subject to change without notice and revision of this document. TI has discontinued the production of the device. Resale of TI components or services with dataasheet different from or beyond the parameters stated by TI for that component or service voids all express and any implied warranties for the associated TI component or service and is an unfair and deceptive business practice.
