The AD847 represents a breakthrough in high speed amplifiers offing superior ac & dc perfomance and low power, all at low cost. The excellent dc performance is demonstrated by its ±5 V specifications which include an open-loop gain of 3500 V/V (500 Ohm load) and low input offset voltage of 0.5 mV. Common-mode rejection is a minimum of 78 dB. Output voltage swing is ±3 V into loads as low as 150 Ohm. Analog Devices also offers over 30 other high speed amplifiers from the low noise AD829 (1.7nV/(root)Hz) to the ultimate video amplifier, the AD811, which features 0.01% differential gain and 0.01° differential phase.

At least one model within this product family is in production and available for purchase. The product is appropriate for new designs but newer alternatives may exist.
Evaluation Kits (1)
The Universal Single High Speed Amplifier Evaluation Boards are bare boards that enable users to quickly prototype a variety of amplifier circuits, which minimizes risk and reduces time to market. These boards are all RoHs Compliant. See ordering guide below on what board to order by lead count and package.
Tools & Simulations
AD847 SPICE Macro Models
Use the Analog Filter Wizard to design low-pass, high-pass, or band-pass filters with actual op amps in minutes. As you progress through the design process, you can observe the characteristics of your filter design from ideal specifications to real world circuit behavior. Quickly evaluate the tradeoffs in op amp specifications - including gain-bandwidth, noise, and supply current – to determine the best filter design for your requirements.
Use Photodiode Wizard to design a transimpedance amplifier circuit to interface with a photodiode. Select a photodiode from the library included in the tool, or enter custom photodiode specifications. Quickly observe tradeoffs between Bandwidth, Peaking (Q), and ENOB/SNR. Modify circuit parameters, and immediately see results in plots for pulse response, frequency response, and noise gain.
A utility to convert between standard units of power measurement and signal strength.
This tool estimates die temperature and power dissipation based on the supply voltages, ambient temperature, load characteristics, and package thermal data.
