TI releases new Burr-Brown audio ADC

TI today introduced a new audio analog-to-digital converter (ADC) capable of capturing clear speech at a distance four times longer than similar products in the industry. The TLV320ADC5140 is a smaller four-channel audio ADC with the same performance in the industry. It is one of three new Burr-Brown? Audio ADC products from TI. It can achieve low distortion recording in noisy environments, and can be used in any environment. Far-field high-fidelity recording.

Smart home systems face the challenge of far-field audio collection. Due to the limited number of microphones and limited signal processing capabilities, existing smart home systems have difficulty capturing and understanding voice commands in a noisy environment. The TLV320ADC5140 can help engineers meet this challenge. It can improve audio acquisition across rooms and enhance the use of high-end smart speakers, sound bars, wireless speakers, high-definition televisions, IP network cameras, teleconferencing systems, and smart appliances. Recognition of difficult to capture voice commands. This ADC expands TI's Burr-Brown premium audio equipment portfolio (including high-performance Class D amplifiers, data converters, and op amps), and also helps engineers save system design costs by reducing the number of microphones in the array.

LV320ADC5140 main features and advantages

With a beamforming system, audio can be clearly captured in any environment: The TLV320ADC5140 has a built-in 120dB dynamic range enhancer (DRE). At the system level, the DRE solution can enhance low-volume audio signals while maintaining low-distortion recordings, even when very close to the speaker output. DRE also improves far-field high-fidelity recording in all environments.

High-quality microphones provide high-quality voice compatibility: The TLV320ADC5140 is the first ADC to fully support the latest high signal-to-noise ratio microphones with more than 106dB of dynamic range.

Leading integration supports multi-functional system design: TLV320ADC5140 can support simultaneous sampling of up to four analog channels or eight digital channels (or a combination thereof) of the microphone input, thereby ensuring system flexibility, as well as gain and phase calibration. Program function to equalize microphone array mismatch. Other features include programmable gain amplifiers, high-pass filters, channel mixing, and linear phase or ultra-low delay filters.

Small size and low system power consumption: The built-in functions of the TLV320ADC5140 can help engineers reduce the burden of digital signal processing tasks, which can reduce the design size without sacrificing system reliability. At 48kHz, the power consumption of each channel is only 9.5mW.
