The AD5764ASUZ is a 16-bit Digital-to-Analog Converter (DAC) from Analog Devices (ADI). It is part of a high-performance family of converters offered by ADI, with the series featuring impressive specifications for precision, resolution, linearity, and channel-to-channel matching.

It is extremely well-suited for a variety of applications, including analog output control for temperature, pressure, and weight systems, digital actuators, closed-loop PID control, and industrial automation, among many others. The ADC also has excellent performance characteristics from a low voltage supply, so it can be implemented in battery-powered systems or lower-voltage, higher-power systems.

The AD5764ASUZ features a two-wire serial communication interface that can be I2C or SPI compatible, depending on the user's requirements. It also has an integrated level-shifter to accommodate control and data signals on either voltage domain. The converter supports a variety of adjustable output ranges, allowing flexibility in the output of the differential voltage and its calibrated output current.

The AD5764ASUZ produces linear, accurate analog output signals over a wide dynamic range by using a R-2R ladder circuit together with an on-chip 16-bit digital-to-analog converter (DAC) and post-filtration sigma-delta modulation circuit. This combination enables a high level of linearity (typically 0.003% or better) and low noise floor. The converter also has selectable output ranges, which range from –2.3 to +2.3 V in 30 mV increments, as well as a high-impedance 50 Ω mode.

The AD5764ASUZ is powered by a 2.5V to 5.5V supply voltage. This low voltage requirement makes the DAC suitable for a variety of applications, such as low-power industrial systems and automotive electronics where low voltage is critical. It also features an integrated reference voltage that is used to set the output voltage range. An external reference voltage can be used if the output range needs to be adjusted.

The AD5764ASUZ offers an improved performance-voltage ratio compared with competing converters, enabling accurate output signals for low-power systems. With fully differential output-voltage range, the device is well-suited for industrial and motor control applications. The device is also optimized for total harmonic distortion (THD) as low as 0.2%, relative to the full scale range. The converter is available in a 16-lead TSSOP package that minimizes power consumption and DC offset, and further enhances the output performance.

The AD5764ASUZ features a variety of features and benefits that make it an ideal solution for a wide range of applications. The versatile design reduces system-level costs, while the low-power consumption and integrated reference allow a flexible design. In addition, its two-wire interface, wide range of adjustable output ranges, and excellent performance characteristics make it an ideal choice for industrial, motor control, and automotive applications.
