AD7729ARUZ-REEL is an integrated circuit (IC) designed for analog-to-digital conversion (ADC). It is embedded with a low-noise, low-power, 14-channel, 16-bit delta-sigma (ΔΣ) ADC that has the capability to convert multiple input signals into digital form. It also has the benefit of two-stage post-processing with no DSP required. The device is ideal for applications that require a wide dynamic range, such as measuring temperature, pressure, or strain, in harsh environments.

AD7729ARUZ-REEL is suitable for multiple-channel data acquisition and control systems, including industrial systems, medical instrumentation, and automotive applications. The device offers a wide range of models and features, including four alternate supply voltages, and is easily connected via an SPI interface. It also supports differential input signals, allowing accurate measurement in noisy or/and high voltage environments.

The device works on a dual-slope peak-detection technique combined with digital post-processing. It performs one analog-to-digital conversion or up to 14 conversions at the same time depending on the mode of operation chosen. It is capable of sampling frequencies from 20 Hz to 4 kHz, making it suitable for fast-responding process measurements. The device also has an internal zero-drift voltage reference for low-cost applications.

AD7729ARUZ-REEL operates in two modes: single-channel or multiple-channel data acquisition. When used in single-channel mode, the device converts a single analog-to-digital signal and then internally runs the post-processing algorithm to generate the Digital Result. In multiple-channel mode, the device performs the conversion, post-processing and then stores all the results in an on-chip memory. The device also features an internal clock which can be used to control the multiple conversions and process the results quickly, thus providing a low-cost solution for high-channel data acquisition applications.

The device is housed in a 20-pin dual flat no-leads (DFN) package, making it compact and easy to use. It also features built-in power management that automatically shuts off the device in case of hardware or software failures, saving power and eliminating the need for user intervention.

Overall, AD7729ARUZ-REEL is a powerful and reliable solution for data acquisition applications that require high-performance conversion and fast response times in harsh environments. With its robust design and a wide array of features, the device is ideal for industrial, medical, and automotive applications.
