Digital to analog converters (DACs) are important components used in signal processing for various applications, ranging from instrumentation to embedded system. In this article, we will discuss the application field and working principle of the DAC8168IAPWR, a 16-bit, low-power, high-resolution DAC with a +2.5V to +5V single supply operating range.

Introduction

The DAC8168IAPWR is part of the popular Texas Instruments DAC family. It is a 16-bit CMOS (complementary metal-oxide semiconductor) digital-to-analog converter specifically designed for telecommunications and control systems. Its 0.3V internal reference voltage ensures accurate and stable outputs. It featuresprogrammable gain settings, integrated logic and an on-board double-buffered serial-to-parallel data converter for increased versatility. The DAC8168IAPWR is capable of providing resolution as low as 0.0015 LSB and a bandwidth of up to 25 MHz.

Applications

The DAC8168IAPWR is used in a variety of applications, ranging from data conversion, communication, signal processing, and especially in instrumentation and embedded systems. The DAC is compatible with PC\'s, DSPs, and microcontrollers and can be used for signal control and signal conditioning applications such as temperature control, noise reduction, signal shaping, and feedback control loop. Because it is low power, it is especially suitable for battery-powered applications. Additionally, its high precision ensures that signals can be generated with minimal distortion.

The DAC8168IAPWR is also gaining popularity in the automotive industry due to its excellent scalability, which makes it suitable for use in control systems, power converters and power amplifiers.

Working Principle

The DAC8168IAPWR works on the principle of voltage-mode conversion. It converts digital information contained in a string of binary words into an analog voltage. Each binary word corresponds to a definite voltage level. As the binary word changes, the output voltage is also changed accordingly.

The DAC consists of an array of capacitors and switches which are connected to the reference voltage. The switches are controlled by the input binary word and the output voltage is determined by the combination of the reference voltage and the capacitor values. The total capacitance of the array can be varied to obtain different gain settings.

Internal logic circuits convert the serial data input into a parallel word which is then loaded into the DAC\'s shift register, where the data is held while the DAC is settling to the output voltage. The DAC is then ready for the next conversion. This double-buffered approach eliminates complicated timing requirements and increases the speed of the entire process.

Conclusion

The DAC8168IAPWR is a low-power, high resolution DAC suitable for a variety of instrumentation and embedded system applications. Its internal 0.3V reference voltage ensures accurate and stable outputs and its double-buffered serial-to-parallel data converter eliminates timing requirements and increases speed. With its low power consumption and scalability, it is becoming increasingly popular in the automotive industry.
