The AD8552ARZ is a single, fully differential, low noise amplifier that packs a denseload of features into a small SSOP package. Ideally suited for instrumentation and dataconversion applications, the AD8552ARZ has a gain bandwidth of 100MHz, lowinput noise of 1.3nV/√Hz and extremely low offset voltage, drift and temperaturecoefficient. The combination of these characteristics makes the AD8552ARZ a perfectchoice for any high performance design.

The AD8552ARZ is operated with a dual-supply voltage, the first half of whichprovides the necessary bias for the on-chip circuitry. This reduces the need for externalcomponents and helps to maintain a high signal-to-noise ratio. The maximumoutput voltage swing is also determined by controlling the magnitude of the biassupply. This feature provides an extra degree of control and can help to avoid overdrivingthe input.

The application range of the AD8552ARZ is even more impressive. It has a wideinput common-mode range and extensive overload protection. This makes the deviceideal for use in applications where large input signals may be encountered. Anadditional feature of the AD8552ARZ is the addition of two output current drivers whichcan improve the output drive capability and minimize distortion. The AD8552ARZ is alsofully programmable, allowing the user to optimize the device for their application.

The working principle of the AD8552ARZ is based on the differential current output principle. When a signal is applied to the input, the differential current is amplified to a voltage signal. This voltage is then converted to current via an output stage in order to drive a load. The differential current amplifier is known for its excellent noise performance and low distortion, making it ideal for precision instrumentation applications.

The AD8552ARZ offers a wide range of features, making it an ideal choice for instrumentation and data conversion applications. It has excellent signal-to-noise performance, extensive overload protection and programmable output current drivers. In addition, its differential current amplifier architecture effectively amplifies small signals with low noise. With its wide input common-mode range and differential current outputs, the AD8552ARZ is the perfect amplifier for any high performance design.
