Data Acquisition - Digital to Analog Converters (DACs) are used in countless applications to convert digital data into analog signals. One such type of DAC is the LTC2631HTS8-HM10#TRMPBF, which is a high-quality 10-bit digital-to-analog converter (DAC) that provides a rail-to-rail voltage output range with a robust power supply rejector. This device features 5 µs settling time, flexible hardware reset pin, and an integrated voltage reference, making it ideal for a variety of high speed applications such as motor control, digital panel meters, audio, and data acquisition systems. Below, we examine the application field and working principle of this DAC.Application FieldThe LTC2631HTS8-HM10#TRMPBF is well-suited for applications such as motor control, digital panel meters, audio, and data acquisition systems.In motor control applications, this DAC can be used to acquire digital signals, such as position and velocity, and convert them into analog voltages that can be used by analog motor controllers to control the motor.In digital panel meters, this DAC allows digital panels to accurately measure and display analog values such as temperature, voltage, and current.In audio systems, this DAC can be used to convert digital audio signals into analog signals that can then be amplified and sent to speakers.Finally, in data acquisition systems, this DAC is used to convert digital data into analog signals for further processing.Working Principle The working principle of the LTC2631HTS8-HM10#TRMPBF DAC is based on the movement of charge from an inverted source to a virtual capacitor. The output analog voltage is determined by the voltage stored on the capacitor. This process begins when the control logic of the device is activated, allowing a slight current to flow from the power source into the virtual capacitor. As the charge is increased, so is the voltage drop across the resistor. This voltage drop causes the output voltage to rise, as long as its value stays within the range of the drain pin.When the output voltage reaches the desired level, the control logic is deactivated, cutting off any further current flow into the virtual capacitor. The charge on the capacitor is then maintained, controlling the output voltage until it is changed manually or the power is cycled.The LTC2631HTS8-HM10#TRMPBF consists of an Analog Input (AI), a Digital Input (DI), and a set of voltage-set pins. The AI is used to control the inverted source current, while the DI is used to set the output voltage. The voltage-set pins are then used to define the output voltage range. The integrated voltage reference means that the DAC is capable of providing rail-to-rail output voltage across its range of 0V to 3.3V.In conclusion, the LTC2631HTS8-HM10#TRMPBF is a high-performance digital-to-analog converter (DAC) that provides a rail-to-rail voltage output range. This DAC is well-suited for applications such as motor control, digital panel meters, audio, and data acquisition systems. Its working principle is based on the movement of charge from an inverted source to a virtual capacitor, where the output analog voltage is determined by the voltage stored on the capacitor.
