The DAC7513N/3KG4 is well-suited for a variety of data acquisition applications. In particular, its low offset, smooth analog output, and wide voltage range make it ideal for use in embedded systems, digital to analog conversion applications, industrial automation, audio and video processing, and many more. Additionally, this device can be used in sensors that require precise analog output accuracy in order to output accurate sensor readings. For example, it can be used in force sensors, pH meters, temperature sensors, and more.

Working Principle

The DAC7513N/3KG4 utilizes a voltage buffered architecture to convert digital values into analog voltages. The device contains 16-bit digital-to-analog conversion circuitry, along with an internal reference for setting the output range. This reference determines the range of the output signal, and can be set to between 0V and 4V. The internal reference voltage is supplied to the DAC through two separate inputs.

When a digital input is applied to the device, the digital data is converted into an analog voltage using an internal digital-to-analog converter (DAC). The internal reference is used to define the output range, ensuring that the output signal is accurately converted into the desired voltage range. The output voltage is then buffered, amplified, and sent to the output pins of the device.

The DAC7513N/3KG4 also includes an on-chip voltage reference, allowing the user to set the output voltage range based on the reference voltage supplied. This reference voltage is also used to set the sleep mode current, providing improved energy efficiency.

Conclusion

The DAC7513N/3KG4 is a robust digital-to-analog converter with excellent precision and accuracy. Its wide supply voltage range and high output resolution make it suitable for a wide range of data acquisition applications. Additionally, its energy efficient sleep mode allows it to reduce power consumption when idle, giving improved battery life and energy efficiency.
