The AD7767BRUZ-2-RL7 is a high-resolution, low-noise, low-power, 24-bit, stereo analog-to-digital converter (ADC). It offers outstanding performance and features for a range of data acquisition applications. The ADC operates from a single +2.7 to +3.6 V power supply and features an internal voltage reference and a wide input-channel bandwidth of up to 2 MHz. It also offers industry-leading low-noise performance, with a programmable noise-shaping filter to reduce the noise floor of the device. In addition, its low-power consumption makes it suitable for use in battery-powered applications.

The ADC has a powerful on-chip processing capabilities, including a programmable decimation filter, combining multiple channels in a single channel input path, providing multiplexing of up to five unipolar/bipolar channels to one channel input path or up to three bipolar/unipolar channels to one channel input path. It also offers an advanced analog low-pass filter with selectable cutoff frequencies from 1.25 to 500 kHz. This allows for an optimal signal-to-noise ratio (SNR) and total harmonic distortion (THD). Furthermore, the ADC implements an on-chip data format converter capable of translating data into various output formats to suit the requirements of different applications.

The AD7767BRUZ-2-RL7 is typically used in portable audio, medical imaging, precision scientific instruments, automotive audio systems, industrial process control, and other data acquisition applications. In audio applications, the ADC offers low noise and low total harmonic distortion (THD), with an SNR of 106 dB, enabling high-quality recordings and playback. In medical imaging applications, its high resolution and low noise make it suitable for capturing intricate details in medical images. In process control systems, it provides reliable and accurate measurements of various physical parameters.

The working principle of the AD7767BRUZ-2-RL7 is based on the conversion of an analog signal into its digital representation. The analog signal is first pre-amplified and anti-alias filtered to remove signal frequencies above the Nyquist limit of the ADC. The filtered signal is then fed to the on-chip or off-chip sample-and-hold circuit. This ensures a snapshot of the input signal is obtained before it is converted to its digital representation by the ADC. The digital representation is then outputted in the appropriate digital format.

The AD7767BRUZ-2-RL7 have multiple power saving modes and on-chip track and hold functions, allowing it to operate efficiently and reliably. Additionally, it is available in packages that are compatible with 24-pin LQFP and SOIC packages. This allows for easy integration into various systems. Overall, the AD7767BRUZ-2-RL7 is an ideal choice for a wide range of data acquisition and audio applications due to its high resolution, low noise, low power consumption, and advanced features.
