AD8802ARZ-REEL, manufactured by Analog Devices, Inc., is a monolithic, 8-bit Digital-to-Analog Converter (DAC). It provides a two channel, serial voltage output on a 28-pin single-in-line package. The device is designed to convert 8-bit digital input words into two analog, 10V full-scale, 10-bit resolution, single-ended current outputs for industrial automation, data acquisition and interface applications.

AD8802ARZ-REEL consists of three principal components an 8-bit shift register, an 8-bit latch, and an 8-bit output DAC core. An external reference voltage is supplied to the DAC core, and the digital input data is provided to the 8-bit shift register. This data is then passed to the 8-bit latch, which stores the input data. Finally, the DAC core converts the input data to analog current outputs according to the supplied reference voltage.

AD8802ARZ-REEL is primarily used in industrial automation and data acquisition applications where precise current control is required. It provides two 10-bit resolution, high speed current output channels with excellent line and load regulation. This makes it suitable for control applications such as servo motor control, industrial machine process control, etc. Additionally, its low power consumption, low cost, and small package make it suitable for hobbyist projects.

AD8802ARZ-REEL features an input data interface with 4 independent logic channels. It accepts 8-bit serial data from the 4 logic channels in 3 different data formats: binary-weighted, octal-weighted, and natural binary. This input data is translated into analog current output by the on-chip DAC core. The device also includes a buffered digital control port that can be used to control various DAC operations, such as low power mode, test/initialization mode, data reset, etc.

In addition to its application in industrial automation and data acquisition, AD8802ARZ-REEL can also be used in communication and interface applications. This versatile device can be used to convert digital communication signals into analog current outputs, enabling communication with legacy systems or devices with an analog interface. It can also be used as a signal transformer or signal conditioner, allowing the conversion of high voltages into current outputs.

In conclusion, AD8802ARZ-REEL is a versatile, low power, and low cost Digital-to-Analog Converter that is suitable for a variety of industrial automation, data acquisition, communication, and interface applications. It features two 10-bit resolution, high-speed current output channels with excellent line and load regulation. It also features 4 independent logic channels for the input data interface and a buffered digital control port for controlling various DAC operations.
