The AD7711AQ is an integrated circuit (IC) component developed by Analog Devices. It is a complete high-resolution analog-to-digital converter (ADC) that is specifically designed for low-frequency measurement applications.
One of the key features of the AD7711AQ is its ability to offer 24-bit resolution over a wide dynamic range, making it suitable for precise measurement applications. It operates on a single-supply voltage ranging from 2.7 volts to 5.25 volts, making it compatible with a wide range of system designs.
The AD7711AQ includes a 3-wire serial interface that allows for easy communication with microcontrollers or other control devices. This interface supports both synchronous and asynchronous communication modes, providing flexibility in different system configurations.
Additionally, the AD7711AQ offers programmable gain and filtering options. The programmable gain amplifier (PGA) allows for amplification of the input analog signals to match the desired measurement range. This feature enhances the versatility of the IC by enabling it to handle a wide variety of input signal amplitudes. The programmable digital filter helps in removing noise and reducing the influence of unwanted signals, resulting in precise and accurate measurements.
The IC also incorporates a self-calibration feature, which ensures accuracy by continuously monitoring and adjusting the internal calibration coefficients. It also includes an on-chip reference voltage and a precision voltage reference pin, eliminating the need for external reference components
