The AD7302BNZ is part of the ADI family of Digital to Analog Converters (DAC) used for Data Acquisition. This product is especially suitable for applications in the industrial and automotive sectors. The device consists of an integrated low noise 6-bit, 8-bit, and 10-bit DAC, signed and unsigned inputs, and a 4-digit LED display which allows for easy configuring.

The AD7302BNZ can be operated from a wide range of single and dual supply voltages, from +3.3V to +5V, making it a versatile and adaptable solution for a wide range of applications. It also has multiple digital inputs for acceptance of 8-bit, 10-bit, 12-bit, and 16-bit parallel inputs and a serial input for 10-bit or 16-bit data.

The AD7302BNZ is an ideal solution for the transfer of analog signals, measurement and control applications, such as pressure and force sensors, temperature sensors, in industrial and automotive products. Its low noise 6, 8, and 10-bit DACs ensure accurate conversion and results. The device has a reference voltage option, which allows connection of either a single-ended or a differential input with up to 200 mV of maximum reference voltage. This allows for accurate conversions, even over long periods of time.

The AD7302BNZ has an output range of 0 to +5V. The internal voltage reference can be programmed to match the reference voltage of the analog source providing better matching of the converted signal. Additionally, a direct 10-bit and 16-bit serial data transmission reduces the need for additional external buffering, reducing system costs.

AD7302BNZ’s working principle is based on the conversion of digital data from parallel or serial inputs into analog voltage levels. The digital inputs are used to control the voltage at the output, which can range from 0V to +5V. The digital data is processed and the digital-to-analog conversion is done using a high-precision low-noise DAC with a linearity of 6, 8 and 10bits and a higher-order DAC register and a multiplexer. The reference voltage option allows connection of either a single-ended or a differential preamp, for conversion of unipolar or bipolar analog inputs.

The AD7302BNZ has several features that make it an attractive solution for data acquisition applications. It has an industry-standard parallel data interface that supports 8-bit and 10-bit inputs, making it easy to interface with other devices and systems. It also provides a 10-bit and 16-bit serial data interface that reduces external buffering requirements. Additionally, it offers adjustable gain for both input and output stages, allowing it to be adapted to various electronic systems. With its low noise, excellent linearity and accuracy, the AD7302BNZ is an ideal solution for many data acquisition systems.
