Data acquisition is the process of sampling signals that measure real-world physical conditions and converting the resulting samples into digital numbers that can be manipulated by a computer. Digital-to-analog converters (DACs) are essential components for such systems, providing a means of producing analog output signals from digital inputs. The AD5668BRUZ-2 is a precision 16-bit, voltage output DAC that can be used in a wide variety of data acquisition applications.

The AD5668BRUZ-2 is an ideal candidate for applications requiring precision multiple channel analog outputs operating from a single supply voltage. The AD5668BRUZ-2 is available with a choice of unipolar or bipolar output ranges, which are independently adjustable via four digital control bits. Additionally, the available output range can be further extended to ±5 V by configuring the output range as B2X and setting the gain limit to maximum output voltage, thus providing a much broader range of analog output signals than those typically provided by other DACs.

The AD5668BRUZ-2 is based on a Delta-Sigma (ΔΣ) architecture, which is often referred to as a ‘1-bit’ architecture, since the input to a ΔΣ DAC is a 1-bit digital signal. The 1-bit input is a pulse width modulated signal, where the width of the pulses is proportional to the desired analog output value. This type of converter is capable of very high resolutions, at the expense of a higher complexity. The AD5668BRUZ-2 offers a resolution of 16-bits, which allows it to provide excellent linearity and accuracy.

The AD5668BRUZ-2 is extremely versatile and offers a wide range of features and functionalities. It features a power-on reset, allowing it to be used in a digital control system without the need for external circuitry. The digital inputs to the AD5668BRUZ-2 are fully TTL and CMOS compatible, and the voltage output range can be configured to either unipolar or bipolar as mentioned earlier. In addition, the AD5668BRUZ-2 offers an adjustable gain limit and can be used with an external reference voltage.

The AD5668BRUZ-2 is a general-purpose 16-bit DAC, suitable for a wide variety of precision data acquisition applications. It offers excellent linearity and accuracy, while its wide input and adjustable output range make it well suited to applications that require high-resolution analog output signals. It also offers excellent stability, making it suitable for use in precision systems, and its TTL and CMOS compatible input allows it to be easily integrated into a digital control system.
