3 nV/√Hz Ultralow Distortion Voltage Feedback High Speed Amplifier

Manufactured by:

Product Details

The AD8045 is a unity gain stable voltage feedback amplifier with ultralow distortion, low noise, and high slew rate. With a spurious-free dynamic range of -90 dBc @ 20 MHz, the AD8045 is an ideal solution in a variety of applications, including ultrasound, ATE, active filters, and ADC drivers. ADI's proprietary next generation XFCB process and innovative architecture enables such high performance amplifiers.

The AD8045 features a low distortion pin out for the LFCSP, which improves second harmonic distortion and simplifies the layout of the circuit board.

The AD8045 amplifier is available in a 3 mm x 3 mm LFCSP as well as the standard 8-lead SOIC. Both packages feature an exposed paddle that provides a low thermal resistance path to the PCB. This enables a more efficient heat transfer, and increases reliability. The AD8045 works over the extended industrial temperature range (-40°C to +125°C).

Evaluation Kits


X +


Product Details

This evaluation board is designed to help users evaluate the AD8045. 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.


EVAL-HSAMP-1 Circuit Diagram

Product Details

The SO8 SINGLE AMP evaluation board aids in the evaluation of single, 8-lead SOIC operational amplifiers. The SO8 SINGLE AMP  evaluation board is a bare board with no components soldered on, which enables users to prototype a variety of operational amplifier circuits. The SO8 SINGLE AMP evaluation board supports any of the Analog Devices, Inc., single operational amplifiers in 8-lead SOIC packages with and without a dedicated feedback pin, an exposed paddle, and an external compensation pin.

The 6-layer evaluation board accepts edge mounted SMA connectors on both inputs and outputs to allow an efficient connection to test equipment and other circuitry.

Optimized power and ground planes ensure low noise and high speed operation. Component placement and power supply bypassing are optimized for maximum circuit flexibility and performance. The evaluation board accepts 0402 or 0603 surface-mount technology (SMT) components, 1206 bypass capacitors, and 100 mil headers.

All components are placed on the primary side. No components are placed on the secondary side.
