The AD7714ARS-5 is a single-channel, low-power 16-bit sigma-delta (Σ-Δ) analog-to-digital converter (ADC) designed for use in applications that require accurate and reliable digitization of voltage and bridge-type transducer measurements. It features a dedicated on-chip amplifier and a user-selectable gain setting of 1 to 32. It occupies only 94 square millimeters of board space and may be used in both low-power CMOS logic systems and higher-powered variants. It supports high-speed, low-latency conversion rates to maximize signal integrity during signal acquisition.

The AD7714ARS-5 operates on a single 2.7V to 5.25V supply power source. Internally, the device contains an advanced signal processing stage which supports various signal measurement specifications. Included is an analog input range from 0 to 4V, with an output range from 0 to 40V. The signal-to-noise ratio (SNR) is -108 dB at a resolution of 16 bits. The device performance is validated for temperatures up to 125°C.

The device employs the sigma-delta (Σ-Δ) architecture to perform the analog-to-digital conversion. In this architecture, an active low-pass filter is used to downsample an analog signal by a factor of two. The low-pass filter is comprised of a comparator and a digital to analog converter (DAC). The comparator compares the sampled signal to a reference voltage loop and provides a digital output that is either high or low based on the reference voltage. The DAC then converts the digital output to an analog voltage that can then be converted to a digital value. This digital value is then used to adjust the gain of the filter.

The AD7714ARS-5 can be used for a variety of applications such as instrumentation and control systems. For example, it can be used to measure and control strain, temperature, pressure, load, velocity, and many other physical phenomena. Additionally, it can be used to process audio and video signals. The wide operating range and precision of the device make it well suited to these applications.

In addition to these applications, the device is also used in medical devices, industrial automation systems, and IoT networks. The AD7714ARS-5 has a number of features that make it suitable for these applications. For example, it features picoamp-level inputs and noise-canceling capability, making it suitable for use in low noise, low power applications. It is also compatible with a variety of serial interfaces, making it compatible with a wide range of serial communication protocols.

Overall, the AD7714ARS-5 is an efficient, low-power and high-precision analog-to-digital converter designed for use in a variety of applications. Its robust design and low-power requirements make it well suited for embedded systems, IoT networks, medical devices, and industrial automation systems. With its low-jitter, low-power performance, the AD7714ARS-5 is the perfect choice for any application requiring high accuracy and reliability.
