AD825

Low Cost, General-Purpose High Speed JFET Amplifier
Manufactured by:

Product Details

The AD825 is a superbly optimized operational amplifier for high speed, low cost and dc parameters, making it ideally suited for a broad range of signal conditioning and data acquisition applications. The ac performance, gain, bandwidth, slew rate and drive capability are all very stable over temperature. The AD825 also maintains stable gain under varying load conditions.

The unique input stage has ultralow input bias current and input current noise. Signals that go to either rail on this high performance input do not cause phase reversals at the output. These features make the AD825 a good choice as a buffer for MUX outputs, creating minimal offset and gain errors.

The AD825 is fully specified for operation with dual ±5 V and ±15 V supplies. This power supply flexibility, and the low supply current of 6.5 mA with excellent ac characteristics under all supply conditions, makes the AD825 well suited for many demanding applications.

Product Details

This evaluation board is designed to help users evaluate the AD825. The evaluation board is a bare board: there are no components or amplifiers soldered to the board. These parts must be obtained separately from the table below or on the product page. Free samples may also be requested. The unpopulated board enables users to quickly customize and prototype a variety of op amp circuits, which minimizes risk and reduces time to market.

The User Guide contains all the required documentation to build the board, including schematics, assembly drawing, and Bill of Materials.

We have been using this amplifier for many years as a long coaxial cable driver. No problem with more than 100m long coaxial cables used for 5-10us pulses transmission (no ringing, unstability etc.).

Low Frequency test
Tested the Wide SOIC, Hot air soldered to test board, very stable and forgiving with less than perfect board design. Impressed.
