Data Acquisition - Digital to Analog Converters (DAC) are specialized analog circuits that convert digital information into an output signal of voltage or current. The DAC902U/1K is an example of such a device, which is a highly configurable, low-cost, 12-bit waveform generator. It is ideal for producing an exact sine wave and provides an easy way to precisely measure signal characteristics.

The DAC902U/1K is a 4-channel voltage D/A converter that operates from 28V supplies. With differential outputs, it provides a resolution of up to 14 bits and a signal to noise ratio of 90 dB at full scale. The device also features an embedded EEPROM that allows the user to store a waveform up to 12 bits wide and 8 points deep. Each waveform can be programmed using the on-chip internal clock source. The waveforms can also be programmed using an external clock signal with a frequency range of up to 10 MHz.

The DAC902U/1K has a versatile output-voltage range with a full-scale range from 0V to 9V. Its low-noise design also minimizes current draw from the analog output, which makes it ideal for applications where a precise waveform is required with minimum noise generation.

As a waveform generator, the DAC902U/1K is ideal for a range of applications in instrumentation and measurement. For example, it can be used to drive a load cell, produce an oscilloscope-like display, and generate analog signals for test equipment. The DAC can also be used to generate a precise sine wave for RF communication systems, basic waveform analysis, and video jitter control.

The DAC902U/1K delivers highly accurate waveforms thanks to its precision output, low jitter and low drift. With its wide range of selectable input frequencies and a programmable digital-to-analog converter, the DAC902U/1K is the perfect solution for generating precise waveforms for testing and measurement applications.

In terms of its working principle, the DAC902U/1K converts its digital input bits into an analogue voltage by summing two different binary numbers multiplied by corresponding voltage factors. The output voltage is calculated by summing the binary outputs multiplied by the corresponding voltage levels. The analog output can then be used to drive the load cell or generate an oscilloscope-like display.

In conclusion, the DAC902U/1K is an ideal solution for a range of instrumentation and measurement applications, providing a precise waveform with low noise and very low jitter. Its wide range of input frequencies makes it suitable for a variety of applications and its embedded EEPROM allows the user to store waveforms up to 12 bits wide and 8 points deep. Thanks to its accuracy and robustness, the DAC902U/1K is an ideal choice for generating a precise waveform with minimal noise generation.
