Unity-Gain Stable, Ultralow Distortion, 1 nV/√Hz Voltage Noise, High Speed Op Amp

Manufactured by:

Product Details

The ADA4899-1 is an ultralow noise (1 nV/√Hz) and distortion (<−117 dBc @1 MHz) unity-gain stable voltage feedback op amp, the combination of which makes it ideal for 16-bit and 18-bit systems. The ADA4899-1 features a linear, low noise input stage and internal compensation that achieves high slew rates and low noise even at unity gain. The Analog Devices, Inc. proprietary next-generation XFCB process and innovative circuit design enable such high performance amplifiers.

The ADA4899-1 drives 100 Ω loads at breakthrough performance levels with only 15 mA of supply current. With the wide supply voltage range (4.5 V to 12 V), low offset voltage (230 μV maxi-mum), wide bandwidth (600 MHz), and slew rate (310 V/μs), the ADA4899-1 is designed to work in the most demanding applications. The ADA4899-1 also features an input bias current cancellation mode that reduces input bias current by a factor of 60.

The ADA4899-1 is available in a 3 mm × 3 mm LFCSP and an 8-lead SOIC package. Both packages feature an exposed metal paddle that improves heat transfer to the ground plane, which is a significant improvement over traditional plastic packages. The ADA4899-1 is rated to work over the extended industrial temperature range, −40°C to +125°C.

Evaluation Kits


X +


Product Details

These evaluation boards are designed to help users evaluate the ADA4899-1. 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.
