The AD7920BKSZ-REEL from Analog Devices is a 10-bit, 32-Sample-and-Hold, Analog-to-Digital Converter (ADC), designed for a wide range of data acquisition applications. The device operates from a single 5V supply and features an internal reference with a buffered voltage output and an additional supply pin for an external reference. Moreover, its key features include serial interface, fast conversion rate, internal sequencer, and sampling rate of 192kHz.

Electrical Characteristics and Working Principle: The ADC features a 10-bit conversion resolution, a minimum sampling rate of 192kHz, and an absolute accuracy of ± 2.5mV. It has an internal reference voltage of 2.5V, and a buffer voltage output of 2.9V ± 0.1V. The device also features an internal sequencer that can sequence up to 32 conversions while operating on an internal clock source. The device is powered by a single 5V supply and can operate over an operating temperature range of -40°C to +85°C.

The AD7920BKSZ-REEL device performs 10-bit analog-to-digital conversion based on a successive approximation register (SAR) ADC design. It uses a counter to compare the input voltage to the reference voltage and then sends a one-bit result. This process is repeated until all 10-bits of the data output is acquired. The internal reference provides a stable reference voltage for sampling, and the reference voltage can also be increased or decreased depending on the desired accuracy.

Applications: The AD7920BKSZ-REEL ADC is ideal for a wide range of signal Acquisition, medical imaging, and industrial monitoring applications. This ADC is well suited for data acquisition applications that require high dynamic performance, such as temperature sensing, vibration sensing, and flow measurement. It can also be used as a digital signal processing device, such as an audio signal processor, signal analytics device, and image processing device.

The AD7920BKSZ-REEL device is available in a 28-pin SOIC package, making it suitable for space-constrained and low-power applications. It has fast data conversion rate and low power consumption, making it a good choice for embedded and portable devices. The device also has several control and status bits available for easy configuration and monitoring. Furthermore, the device is RoHS, REACH, and Conflict Minerals compliant and has passed several tests to ensure its reliable operation.

In summary, the AD7920BKSZ-REEL is an ideal solution for a wide range of high-precision data acquisition applications. It operates with a single 5V supply and features 10-bit resolution and an absolute accuracy of ±2.5mV. This device is highly suitable for applications that require fast conversion rate, low power consumption, and small form factor. In addition, the device has several control and status bits, making it easy to configure and monitor.
