Introduction

The TLV320AIC23BGQE (TLV320AIC23) is a high performance, low power audio CODEC with integrated headphone amplifier and optional external microphone amplifiers. It includes a 24-bit analog to digital converter (ADC) and digital to analog converter (DAC). The combination of a low power digital signal processor (DSP) and digital engine makes it ideal for portable audio applications like MP3 and MID players, mobile phones, laptops, PDAs, and more. The device also features two built-in Class-D power amplifiers, which allow Headphone and Speaker operation. Its built-in DAC and ADC make it suitable for recording, editing and mixing audio sources.

Application Field

TLV320AIC23BGQE is suitable for audio application like MP3 and MID players, mobile phones, laptops, PDAs, and more. The device can also be used for applications such as video conferencing, and video streaming. It can work with 2 stereo line inputs, speakers and headphones, microphone inputs and line outputs too.Due to its built-in 24 bit ADC, the device provides high signal to noise ratio and low distortion for recording, editing and mixing audio signal, as well as for other applications such as video or voice conferencing systems.The device’s low power consumption makes it ideal for battery-powered devices, such as mobile phones and MID players.

Working Principle

TLV320AIC23BGQE is a high performance, low power audio CODEC with integrated headphone amplifier and optional external microphone amplifiers. It includes a 24-bit analog to digital converter (ADC) and digital to analog converter (DAC). It works on the principle of sampling and data conversion, which involves digitizing the input signal and reconstructing it into an analog form.In the ADC, incoming analog signals are sampled at a set rate and converted into digital bits. The digital bits are then passed to the audio processor, where the signal is processed for noise reduction and various other operations. The processed digital signal is then sent to the DAC, which converts it back into an analog form for further amplification.TLV320AIC23BGQE also includes a DSP for signal processing, such as noise reduction or dynamic range compression.

Conclusion

The TLV320AIC23BGQE is a high performance and low power audio CODEC with integrated headphone amplifier and optional external microphone amplifiers. It is ideal for portable audio applications like MP3 and MID players, mobile phones, laptops, PDAs and more. Its 24-bit ADC and DAC provide high sound quality and excellent signal to noise ratio. The device’s low power consumption makes it suitable for battery-powered applications, such as mobile phones and MID players. It is also suitable for applications such as video conferencing, and video streaming.
