Frequently Asked Questions
What sample-rate range does the TLV320ADC3120IRTER support for audio acquisition?
The TLV320ADC3120IRTER supports audio sample rates from 7.35 kHz up to 768 kHz, covering standard rates such as 44.1 kHz, 48 kHz, 96 kHz, 192 kHz, and beyond. This wide range makes it suitable for both standard consumer audio and high-resolution professional recording applications in a single 32-bit converter design.
How does the TDM interface on the TLV320ADC3120IRTER benefit multi-microphone designs?
The TDM (Time-Division Multiplexed) interface allows multiple TLV320ADC3120IRTER converters to share a single 4-wire serial bus, reducing GPIO and routing overhead by carrying up to 8 channels of 32-bit audio data on one data line. This is especially valuable in 4- or 8-microphone far-field voice arrays where board space and MCU pin count are constrained.
Is the TLV320ADC3120IRTER suitable for automotive infotainment systems?
Yes, the TLV320ADC3120IRTER is rated -40°C to 125°C, meeting the thermal requirements of automotive infotainment, in-cabin voice recognition, and noise-cancellation modules. Its 1.9 V maximum analog input voltage is compatible with MEMS microphone outputs, and the 20-pin WQFN 3x3 mm footprint fits within tight automotive PCB layouts.
What is the resolution of the TLV320ADC3120IRTER and how does it compare to 24-bit audio ADCs?
The TLV320ADC3120IRTER delivers 32-bit binary-coded output words from its delta-sigma converter, offering 8 additional bits of dynamic range headroom compared to 24-bit ADCs. This extra resolution simplifies gain-stage design by providing margin for digital volume control without sacrificing signal-to-noise ratio in studio recording or precision measurement applications.
