PCM1781DBQR application field and working principlePCM1781DBQR is a high performance and advanced precision digital-to-analog converter (DAC) designed by Texas Instruments. It is an 8-channel single-ended (14-bit) DAC with a differential-voltage output with full TTL digital input capability. PCM1781DBQR is an advanced integrated circuit designed to offer outstanding precision digital-to-analog conversion, wide dynamic range and optimal power dissipation. It offers excellent output polarity, low noise and distortion levels, and full TTL compatibility.The 8-channel DAC’s have several applications in the embedded and communications markets, such as in audio applications, measuring instruments, embedded communication systems, industrial process control systems, home theater, instrumentation and oscilloscopes, motor/motion control, medical/healthcare, and audio and video systems.The PCM1781DBQR is also widely used in high-end digital recording systems due to its high resolution and precise output. It supports multiple digital audio recording standards, such as AES/EBU, ADAT, and SDIF. In addition, it can be used to create multi-channel analog outputs for audio systems.In terms of its working principle, PCM1781DBQR uses a multibit scheme of Sigma-Delta modulation. This type of oversampling method works on the principle that the signal is sampled at a much higher rate than its original rate. This is done to increase the resolution of the data as it is converted from digital to analog.The high-resolution output of the PCM1781DBQR enables it to accurately represent the analog signal being converted. The high sampling rate allows for a wide range of frequency response, which enables high-quality audio performance.Other applications that require precision digital-to-analog conversion, such as in motor control and medical imaging, also use the PCM1781DBQR. The device is used in motor controllers to accurately turn the motor on and off in response to digital signals. It is also used in medical imaging to provide precise digital-to-analog conversion of raw data.PCM1781DBQR also offers superior power efficiency. Its low-power architecture has been designed to minimize power consumption, while also providing optimal performance.In summary, PCM1781DBQR is an advanced and high-performance digital-to-analog converter that is used in a wide range of applications. It offers excellent precision, full TTL digital input compatibility, wide dynamic range and optimal power consumption.
