Working Principles

The AD8007AR is a voltage feedback amplifier that utilizes a differential input stage followed by a gain stage. The differential input stage provides high common-mode rejection, while the gain stage amplifies the differential signal. The amplifier operates in class AB, allowing it to achieve both high linearity and low distortion.

Application Field Plans

The AD8007AR is commonly used in the following applications:

1. Video Distribution Amplifiers
2. Professional Audio Equipment
3. Test and Measurement Instruments
4. Communication Systems
5. Medical Imaging Devices
