4-channel audio ADC with 768k SPS and dual supply
The TLV320ADC6140IRTWT is a 4-channel audio ADC from Texas Instruments, sampling at 768k per second — this puts it in the wide-band audio capture class, covering microphone arrays, beamforming, and high-fidelity recording where the Nyquist ceiling needs to stay above 350 kHz. Control and data transfer go through either I²C or SPI, selectable at power-up — the I²C bus handles register configuration, while the audio data stream is typically read over SPI at the higher clock rates needed for 768k SPS throughput.
Housed in a 24-WFQFN with an exposed pad (4x4 mm body, supplier device package 24-WQFN).
Active lifecycle and compliance posture
ROHS3 compliant — no restricted substances above the threshold limits, and the part carries the full TI compliance documentation (RoHS, REACH, conflict minerals declaration) available through the standard support portal.
