Data Acquisition is a process that detects and records conditions of a certain environment. It involves the conversion of analog digital signals from one form to another. Analog to Digital Converters (ADC) are used to perform such conversions, and the AD7651ACPZRL is one such device.

The AD7651ACPZRL is a low-power 14-bit Analog-to-Digital Converter that operates over a wide supply range from 2.7V to 5.5 V. It provides a fast conversion rate of up to 500 kSPS and an SNR of 113 dB. It features a single-cycle conversion architecture and a low-power sleep mode, making it ideal for portable and battery-operated systems.

Its application field includes medical imaging and instrumentation, such as medical interface, remote patient monitoring and laboratory equipment. It is also suitable for many audio applications, telecommunications, automotive, and green technology products.

The working principle of the AD7651ACPZRL is relatively simple. When the input signal comes in, it is compared to an internal reference voltage, and then converted into a binary number. This number is then stored in an onboard register and is read out by a serial interface.

The main features of the device include a wide input dynamic range with a short input time constant, an onboard analog reference and gain setting options, digital and analog filters, a fast conversion rate, a low-power sleep mode, and a wide supply range from 2.7 V to 5.5 V.

In summary, the AD7651ACPZRL is a low-power 14-bit Analog-to-Digital Converter that operates over a wide supply range from 2.7V to 5.5 V. It provides a fast conversion rate of up to 500 kSPS and an SNR of 113 dB. Its application field includes medical imaging and instrumentation, such as medical interface, remote patient monitoring and laboratory equipment. The working principle is relatively simple, it compares an input signal to an internal reference voltage, and then stores the resulting binary number in an onboard register.
