The AD5346BRU is a contemporary digital-to-analog converter that is part of the Data Acquisition - Digital to Analog Converters (DAC) field. Its versatility is highlighted by the ability to accept both single-ended and differential analog inputs and deliver a dynamic range of up to 16 bits with a maximum settling time of 300 ns.

This high-speed DAC takes a digital input as either a parallel or serial byte and converts it instantly into an analog output. It is also designed to be compatible with a wide variety of logic families and allows for single-induced linear analog inputs, as well as differential inputs of up to 1.75 Vp-p. The AD5346BRU also includes an on-board reference and enables a successful input and output connection without additional circuitry.

The DAC is available in an 8-pin SOIC footprint and has an operating temperature range between –40 °C and +105 °C, making it suitable for a variety of commercial and industrial applications. These include the design of power converters, digital signal processing, devices with multiple output bits and a wide range of data acquisition and signal conditioning products, such as signal processing systems, amplifiers and audio products. The AD5346BRU DAC is also popular for use in military and aerospace electronics.

The working principle of the AD5346BRU is based on the conversion of the digital word from a memory or a microcontroller, into an analog voltage output. This process is achieved by converting the digital word into a quantized voltage level directly, depending on the resolution of the DAC. As such, the AD5346BRU has a resolution of 16 bits and a dynamic range up to 2 voltage levels. An internal logic block processes the digital words and translates them into a series of discrete voltage levels, which can be interpreted as digital-to-analog conversion process. A low resistance transistor amplifier is used to convert the digital information into an analog signal and a feedback network is used to reduce non-linearity, jitter and noise. Although the AD5346BRU DAC utilizes a low power on-board reference, the maximum output voltage is regulated by the current generated by internal bias sources.

The AD5346BRU is an ideal choice for applications requiring a high resolution single-ended or differential analog output. Its high-speed operation and compatibility with a wide range of logic families makes it suitable for a number of commercial and industrial applications. With a maximum settling time of 300 ns, it provides accurate and consistent voltage output in both single and multi-bit applications.
