The TLV320ADC3001IYZHR, developed by Texas Instruments(TI), is a low-power audio analog-to-digital converter (ADC). With its stereo differential inputs, single-ended microphone inputs and support for sample rates up to 192 kHz, this device provides exceptional audio performance in consumer, automotive and portable application fields. The TLV320ADC3001IYZHR is a stereo differential-input ADC with a double-precision digital signal processor (DSP) and digital-to-analog converter (DAC) functionality. In this article, we will discuss the fields of application and the working principle of the TLV320ADC3001IYZHR.

Fields of Application

The TLV320ADC3001IYZHR is suitable for a wide range of applications in consumer, automotive and portable products and systems. This device is specifically designed for use in consumer phones, such as mobile phones and VoIP applications. It’s also suitable for automotive applications, such as navigation systems, rearview cameras, occupant safety systems and in-car entertainment. In addition, the TLV320ADC3001IYZHR can be used in portable and wearable applications, such as audio headsets, wearable health trackers and hearing aids.

The TLV320ADC3001IYZHR is particularly well-suited for consumer, automotive and portable applications because of its unique features. This device is capable of achieving exceptional audio performance with its single-ended microphone input, dual differential inputs and its low power draw. It also supports sample rates up to 192 kHz for high-fidelity sound reproduction. The power draw of the device is optimised for battery-powered applications, and it has a low pin count for easier board layout.

Working Principle

The TLV320ADC3001IYZHR utilises audio-specific signal processing functions to improve its audio performance. This device utilises a multi-stage signal processing chain to reduce interference, noise and jitter. The first stage is a signal pre-processor, which eliminates interference prior to the ADC. This signal pre-processor reduces the signal-to-noise ratio (SNR) of the signal, improving the dynamic range of the analog-to-digital conversion.

The second stage is a 3-bit delta-sigma ADC, which samples the analog signal and converts it into a digital signal. This ADC operates at a sample rate up to 192 kHz, so it can support high-fidelity sound reproduction.

The third stage is a digital signal processor (DSP), which adjusts the digital signal to optimise its audio performance. This DSP also performs digital-to-analog conversion (DAC) to output the audio signal to the headphoned or speakers. It also features advanced features such as acoustic shock protection, noise shaping and dither, as well as an Automatic Level Control (ALC) for better bass response.

Finally, the TLV320ADC3001IYZHR has a power management unit (PMU), which is responsible for managing the device’s power requirements. This PMU can optimise the device’s power draw for battery-powered applications, allowing it to achieve a long battery life. It also has a low pin count for easier board layout.

Conclusion

The TLV320ADC3001IYZHR is a low-power audio analog-to-digital converter. This device is suitable for a wide range of applications in consumer, automotive and portable products and systems, due to its exceptional audio performance, low power draw and support for sample rates up to 192kHz. It utilises a multi-stage signal processing chain to reduce interference, noise, and jitter and improved the SNR of the signal. Additionally, it features a power management unit to improve its battery life. Consequently, with its range of features and low power draw, the TLV320ADC3001IYZHR is suitable for all types of applications.
