The AD80066KRSZRL is an ultra-small, low power, low-noise differential amplifier suitable for use as an interface between sensors, detectors and other electronic devices. It is built on a single chip monolithic structure and can operate over a wide temperature range. The device is optimized for use in low-cost, low-power and low-noise applications such as hearing aids, medical diagnostics, and industrial instrumentation.

Application Field

The AD80066KRSZRL is well suited for a wide range of applications, including:

• Differential Recording or Signal Conditioning;
• Medical Instrumentation and Diagnostics;
• Hearing Aids;
• Industrial Instrumentation;
• Inertial Sensing;
• Low-Noise Voltage Measurement.

The device also features a very low input current noise figure of 2.75nV/√Hz (Typical) and a wideband gain bandwidth product of 375 kHz, making it ideal for high-resolution signals.

Working Principle

The device works by using a differential amplifier topology to provide high common-mode input voltage range, high CMRR, large their gains, and low output noise. This topology also provides a high input impedance (~10 GΩ) and low output impedance (~50 Ω), enabling the device to accurately condition signals from a variety of sensors, detectors, and other electronic devices.

The device is calibrated and temperature-compensated for precise gain accuracy. It also features a wide operating range of ±12V, making it suitable for use in high-voltage and ESD-sensitive applications. The device includes a rail-to-rail output driver that allows a full-scale voltage swing of ±12V.

In addition to the amplifier, the device also includes a low power shutdown mode that can be activated by an external pull-down logic, allowing for efficient power management in battery-powered or low power applications.

The AD80066KRSZRL is an ideal choice for low power and low-noise differential interface applications, such as hearing aids, medical diagnostics, and other instrumentation, providing high performance and reliable data acquisition.
