Analog to Digital Converters (ADC) are used for the acquisition of data in a wide range of applications, from medical and industrial to consumer, automotive and aerospace. The AD9223ARZ-REEL is an easy-to-use, low power and high linearity analog to digital converter from Analog Devices, Inc. The AD9223ARZ-REEL is an 8-bit successive-approximation (SAR) ADC and a single-ended input with a 0 to 3.3V range, making it ideal for applications requiring low power and high precision.

The AD9223ARZ-REEL features a wide-ranging sampling rate of up to 200 MSPS, enabling accurate data capture with very low power consumption and a high noise free dynamic range (NFR) of 70dB. It also features a number of on-chip components that enhance performance, such as an adjustable single-ended reference buffer (ADC Reffer) and a programmable gain amplifier (PGA). The AD9223ARZ-REEL also offers a variety of options for accommodating different input signals and power management. With an integrated temperature sensor and feedback loops for automatic thermal settling, the AD9223ARZ-REEL allows for efficient thermal management.

The AD9223ARZ-REEL operates on a single-supply that eliminates costly compensation components. The power efficiency of the device is further improved by the integrated voltage regulators and self-clocking features that support a variety of low-power operating modes. This allows for further flexibility in power management, reducing system power and cost. The AD9223ARZ-REEL also features a flexible I/O interface that allows for easy interfacing and integration with devices, including MCUs and DSPs.

The AD9223ARZ-REEL is well suited for a range of data acquisition applications, from automotive and factory automation to medical imaging and imaging systems. The high speed of the device, low power consumption and high linearity make it ideal for applications such as digital cameras and video equipment, wireless communication systems and wireless sensing devices. Furthermore, the AD9223ARZ-REEL can also be used for numerous applications in industrial automation, such as in process control and motor control.

The design of the AD9223ARZ-REEL takes advantage of the SAR architecture to realize a highly linear, low-power, 8-bit ADC, while retaining excellent noise-free dynamic range performance. The SAR process begins with the comparison done by the comparator which compares the sample-and-hold (S&H) input signal to an inverted reference voltage generated by an internal DAC. Depending on the result of the comparison, the MSB (most significant bit) of the ADC is sampled and then the process repeats itself until all 8 bits have been sampled. The advantage of the SAR architecture is that the number of required digital memory elements is minimized.

The AD9223ARZ-REEL is an easy-to-use and cost-effective ADC solution for many applications. With low power consumption, high linearity, wide-ranging sampling rate, integrated voltage regulators and self-clocking features, the AD9223ARZ-REEL is an ideal choice for data acquisition applications such as digital cameras, wireless communication systems and industrial automation.
