The AD8033AR is a low-power, low-voltage, single-supply Amplifier with unique features. It can operate at single supply voltages as low as 1.8 V while also providing a high output voltage swing down to ground. Its wide bandwidth and high slew rate make it an ideal choice for precision instrumentation amplifiers, such as current sense amplifiers and transimpedance amplifiers. In addition, the unique design of the AD8033AR allows it to operate up to 600 MHz, enabling it to be used for high-speed sampling applications.

The AD8033AR provides a wide range of gain configurations with single-ended, differential and RF output modes. Its low-noise, low-distortion and high slew rate characteristics make it ideal for applications where high linearity is required, such as video and audio systems, image processing, medical instrumentation and scientific data acquisition.

The gain of the AD8033AR is programmed by means of a single positive control voltage (VCTRL). The gain may be adjusted over a range of 0 dB to 63 dB in 0.5 dB steps.

The AD8033AR effectively eliminates the need for an external, expensive op amp in low-voltage, low power, single-supply designs. Its low-current requirement of only 7 mA makes it feasible to use single supply +1.8 V operation. Its low voltage requirement also makes it suitable for portable and battery-powered applications.

The AD8033AR features an optimized frequency compensated internal compensation network that is driven by the current sources inside the core amplifier. This allows for a simple and stable feedback loop design even when the external components are both switched and unswitched.

The AD8033AR can be configured for single-ended, differential, or(floating-input) RF output and can drive high-capacitive loads. The AD8033AR also provides an amplifier output that, when shorted to ground, effectively turns off any input signal.

The AD8033AR also features integrated clamp protection against input, output and power supply overvoltage conditions.

The AD8033AR has the capability of a very wide input and output voltage range. This range extends up to ±13 V while the common-mode voltage range is 5 V, allowing a wide range of multiple supply voltages. The output current capability is also high, allowing it to drive capacitive loads up to 10 nF with no distortion or excessive noise.

The AD8033AR provides low-noise, low-distortion performance in high-dynamic range applications. Its wide bandwidth, high slew rate and low output offset voltage make it an ideal choice for driving video and audio systems, image processing and instrumentation applications.

The AD8033AR operates from a single power supply and requires only 8.2 mA of supply current. This allows designers to use the device in both low-power and battery-powered applications.

In summary, the AD8033AR is a low-power, low-voltage, single-supply amplifier with unique features including wide bandwidth, high slew rate, low noise, low distortion, and a wide input/output voltage/current range. Its low-current requirement, wide range of gains available, and integrated clamp protection make it an ideal choice for precision instrumentation amplifiers, audio and video systems, image processing, medical instrumentation, and scientific data acquisition.
