AD8027

Low Distortion, High Speed Rail-to-Rail Input/Output Amplifier
Manufactured by:

Product Details

The AD8027/AD8028 are high speed amplifiers with rail-to-rail input and output that operate on low supply voltages and are optimized for high performance and a wide dynamic signal range. The AD8027/AD8028 have low noise (4.3 nV/√Hz, 1.6 pA/√Hz) and low distortion (120 dBc at 1 MHz). In applications that use a fraction of or use the entire input dynamic range and require low distortion, the AD8027/AD8028 are ideal choices.

Many rail-to-rail input amplifiers have an input stage that switches from one differential pair to another as the input signal crosses a threshold voltage, which causes distortion. The AD8027/AD8028 have a unique feature that allows the user to select the input crossover threshold voltage through the DISABLE/SELECT pin (DISABLE/SELECT x in the 10-lead MSOP, hereafter referred to as DISABLE/SELECT throughout this data sheet). This feature controls the voltage at which the complementary transistor input pairs switch. The AD8027/AD8028 also have intrinsically low crossover distortion.

With their wide supply voltage range (2.7 V to 12 V) and wide bandwidth (190 MHz), the AD8027/AD8028 amplifiers are designed to work in a variety of applications where speed and performance are needed on low supply voltages. The high performance of the AD8027/AD8028 is achieved with a quiescent current of only 6.5 mA (typical) per amplifier. The AD8027/AD8028 have a shutdown mode that is controlled via the DISABLE/SELECT pin.

The AD8027/AD8028 are available in 8-lead SOIC, 6-lead SOT-23, and 10-lead MSOP packages. The AD8028WARMZ-R7 is an automotive grade version, qualified for automotive applications. See the Automotive Products section for more details. The AD8027/AD8028 family is designed to work over the extended temperature range of −40°C to +125°C.

Product Details

This evaluation board is designed to help users evaluate the AD8027. 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.

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.
