Engineers can now achieve a 120-dB dynamic range for clear, high-fidelity audio in smart home applications
Texas Instruments (TI) introduced a new audio analog-to-digital converter (ADC) capable of capturing clear audio up to four times farther away than competing devices. The TLV320ADC5140 is the industry’s smallest quad-channel audio ADC with this level of performance. The device is part of a new family of three TI Burr-Brown™ audio ADCs that enable low-distortion audio recordings in loud environments, along with far-field, high-fidelity recordings in any environment.
Smart home systems face challenges with far-field audio capture. In today’s systems, a limited number of microphones and restricted signal processing capability make it difficult to capture and understand voice commands in loud environments. To meet this challenge, the TLV320ADC5140 enables engineers to improve audio capture from across rooms and boost recognition of soft-spoken commands in applications such as high-end smart speakers, sound bars, wireless speakers, high definition TVs, IP network cameras, teleconferencing systems and smart appliances. The ADC, which joins the portfolio of TI Burr-Brown premium audio devices, including high-performance Class-D amplifiers, data converters and operational amplifiers, can also help engineers save system design costs by reducing the number of microphones in the array.
The TLV320ADC5140 is available now through the TI store. Offered in 4-mm-by-4-mm, 24-pin wafer quad flatpack no-lead (WQFN) packaging, it is priced at US$2.99 in 1,000-unit quantities. The TLV320ADC5140 quad-channel 768-kHz TI Burr-Brown™ audio ADC evaluation module, ADC5140EVM-PDK, is available for $199 in limited quantities.
