The MC14LC5480ENR2 chip is a Quad Channel Digital Access Control (QDAC) chip from Texas Instruments, specifically designed for encoding and decoding of digital audio. In this application note, we will explore the application fields and working principles of the MC14LC5480ENR2.

The MC14LC5480ENR2 chip is a highly integrated device, combining four advanced D/A and A/D conversion in one chip. Its integrated high speed microcontroller allows for independent analog and digital control of each ADC and DAC channel. Each channel supports both 8 and 16 bit data conversion and allows for mono and stereo conversion. The chip also provides acoustic echo cancellation and advanced noise reduction capabilities, allowing it to support digital audio formats ranging from MP3 to AC-3.

The MC14LC5480ENR2 is typically used in digital recording, gaming, and audio streaming applications. The chip operates at data rates up to 8-channel, 24-bit, 192 KHz and supports both Fixed Rate and Variable Rate (VBR). The integrated AGC, AEC, and ANR capabilities allow it to work at optimal levels of performance, with low power and low latency.

The working principle of the MC14LC5480ENR2 is based on the D/A and A/D conversion process. All analog to digital and digital to analog conversions are done within the chip, eliminating the need for conversion chips and delivering a high quality output with minimal power consumption. The integrated microcontroller controls the analog and digital signals for each channel, allowing for independent operation and programmable parameters for each channel.

The chip’s design is highly scalable, allowing for easy integration of additional channels and higher data rates. The digital pins of the MC14LC5480ENR2 are directly coupled to the digital audio ports, simplifying the design of multi-channel applications and further reducing power consumption.

The MC14LC5480ENR2 is a highly integrated and powerful audio CODEC solution. It offers great performance and power savings, making it ideal for digital recording and audio streaming applications. The highly integrated microcontroller and digital interface increase the system’s scalability and flexibility, while the integrated AEC, ANR, and AGC capabilities allow it to work at optimal levels of performance.
