The resolution of a DAC is one of its most important performance indicators. It indicates the smallest amount of signal variation that the converter can distinguish, and is usually expressed in bits.
The sampling rate of a DAC refers to the rate at which a digital signal is converted to an analogue signal.
The output voltage range of a DAC refers to the amplitude range of the analogue signal that is converted from a digital signal.
Some DACs can include other functions such as amplifiers, filters, etc. to improve system integration.
Role of DAC: Converts digital signals to analogue signals so that they can be processed by analogue circuits or analogue devices such as sensors. DACs are used to convert digital signals to analogue signals for speaker output. In automation control systems, DACs are used to control the analogue inputs of actuators.
DACs are widely used in embedded systems such as medical devices, industrial controls, etc. to convert and process digital and analogue signals.
DACs typically offer a variety of interface options for compatibility with a wide range of digital systems and controllers, such as I2C, SPI, UART, and others.
Audio Processing: DACs are typically used in audio devices, such as digital-to-analogue converters, to convert digital audio signals back into analogue form for playback.
Video Processing: DACs are used in video processing equipment to convert digital video signals back to analogue form for display on an analogue monitor or television.
Motor Control: DACs are used in motor control systems to generate analogue signals to drive motors or other electromechanical devices.
Test and Measurement: DACs are used in test and measurement instruments to generate signals for test and calibration purposes.
