The AD7874ARZ-REEL is a data acquisition ADC and DAC that is designed for use with microprocessor-based systems for applications for single or multiple channels in communication, medical, industrial control, and instrumentation systems. It is a special-purpose data acquisition component that is designed for use in difficult to reach locations and in situations where low power is a primary concern.The AD7874ARZ-REEL features a 5-bit analog-to-digital converter (ADC) and a 10-bit digital-to-analog converter (DAC). The ADC has a typical resolution of 8-bit differential, while the DAC has a maximum accuracy of 10-bit. The device has low power consumption and is suitable for battery-powered applications.The AD7874ARZ-REEL has been optimized for applications such as single-ended analog input measurements, flow rate measurement, and temperature measurement. The ADC and DAC are both controlled by a SPI interface, providing the flexibility to program and configure the device for various measurement applications. One of the unique features of the AD7874ARZ-REEL is its onboard low-pass filter. This filter eliminates noise and distortion that can occur when measuring high-frequency signals. It also helps reduce power consumption since the downstream components do not need to be as powerful.The AD7874ARZ-REEL also features an integrated temperature sensor. This allows for low-cost, accurate temperature monitoring and compensation of the device. This is especially useful for applications that require precise temperature control, such as medical equipment. The AD7874ARZ-REEL is also programmable for remote sensing applications. It can be programmed for two-wire or four-wire operation, which allows for remote temperature sensing or remote voltage sensing. With the two-wire operation, the device can be programmed to automatically adjust the output voltage to compensate for temperature fluctuations.The ADC and DAC on the AD7874ARZ-REEL are digitally calibrated to ensure accuracy and reproducibility between devices. The device also features a programmable watchdog timer to provide additional safety features in case of a power failure or an accidental reset.Overall, the AD7874ARZ-REEL is an ideal data acquisition component for applications requiring low power consumption, accuracy, and reproducibility. It is capable of providing high resolution, low power measurements in communications, medical, industrial control, and instrumentation systems, making it a great choice for many measurement applications.
