The AD5781BRUZ is a digitally controlled 16-bit current output DAC with a precision temperature-stabilised reference that offers ideal performance for industrial applications like temperature control, agricultural and automotive applications, automotive instrumentation and compression testing. The AD5781BRUZ is a 16-bit monopolar DAC and can be used for a wide range of voltage and current output for digital to analog conversion.

The AD5781BRUZ is a versatile DAC allowing for precision current and/or voltage output control over both a balanced and unbalanced bridge power configuration. It is temperature-stabilised reference buffered using an integrator to provide up to 1mA current output with a resolution of 0.5 mV. The DAC can operate in the TTL/CMOS voltage range of 0V to 5V with a TTL data throughput of 1 MHz. The reference voltage (V REF ) input is available on the ADC5800 and is externally adjustable by the user, therefore providing a wide range of V REF adjustment range.

The DAC supports a wide range of voltage and current outputs, including bipolar output ranging from 0 to ±2.5V and up to 4mA. It also includes a 16-bit high-precision temperature compensated DAC that features a low noise and low temperature drift of 0.001%. The AD5781BRUZ also comes with an integrated linearity trim feature for easy digital trimming of the ramp and step responses.

The working principle of the AD5781BRUZ is based on the use of a binary weighted DAC architecture. It comprises a DC network of fixed resistor elements connected between the reference voltage and ground, together with the internal DAC output buffer. The input digital word is applied to the DAC switches, resulting in an appropriately weighted voltage of the reference voltage which is then outputted from the DAC output buffer. This can be used to generate an analog current or voltage output.

The AD5781BRUZ is suitable for a broad range of industrial automation and gaging applications, temperature control, automotive instrumentation, agriculture and compression testing, due to its wide range of performance capabilities. It offers reliable, accurate and precise output levels, high linearity and fast response times. Furthermore, its wide operating voltage range and reference voltage flexibility allows for easy and effective compensation of the power supply and temperature drift errors.

In conclusion, the AD5781BRUZ is an ideal choice for industrial applications requiring precise digital to analog conversion, where accuracy and linearity are paramount. It is a reliable, fast, and versatile DAC designed for precision current and/or voltage output control over both balanced and unbalanced bridge power configurations, offering an excellent degree of accuracy and linearity. The device\'s flexible external reference and wide operating voltage range simplify power supply and temperature drift compensation.
