AD7888BR-REEL is an eight-channel, low-power, integrated, 10-bit analog-to-digital converter (ADC) with a voltage reference from Intersil Corporation. It offers multiple redundant 8-bit value configurations, along with I/O isolation and a variety of control options to support application-specific requirements. The device is simple to use and provides a cost effective solution.

The AD7888BR-REEL is designed to convert analog signals from multiple sources into digital signals that can be processed and controlled by computing systems or microprocessors. Applications of the device include data acquisition, instrumentation, industrial control, medical imaging systems, and automotive control. It is also suitable for use in battery-powered systems and any application that requires low power consumption.

The operational features of the AD7888BR-REEL include 10-bit resolution, an 8-channel multiplexer, a 50Khz Sampling Rate, and an I/O isolation feature. The on-chip voltage reference eliminates the need for a separate reference voltage, and can be programmed in the OFF mode to reduce power consumption. An integrated SENSE pin provides system-level feedback for improved accuracy. In addition, the device offers the flexibility of on-chip temperature compensation, offset and gain compensation, and clock generation.

The AD7888BR-REEL has a sigma-delta A/D converter, which converts an analog signal into discrete digital words. It works by sampling an analog input signal and processing the signal using a two step process. First, the signal is oversampled and compared against a reference voltage. The oversampling allows the sigma-delta modulator to self-correct for any errors that occur during the conversion process. Second, the signal is digitally filtered to remove unwanted noise from the output of the modulator, resulting in a more accurate conversion.

The device is designed to run from a single 3.3V supply and draw very low power. It also contains a protection circuitry to protect the device from overvoltage and short-circuit conditions. The AD7888BR-REEL is offered in a JEDEC 16 pin SOIC package which is suitable for use in PC boards and embedded applications.

In conclusion, the AD7888BR-REEL is an ideal analog-to-digital converter with multiple complex features and capabilities that enable it to effectively function in various data acquisition, instrumentation, industrial control, medical imaging, and automotive applications. Its low power consumption, high precision, and reliable performance make it suitable for use in a wide variety of applications.
