TAC5311WQRTVRQ1

Codecs Overview

The TAC5311WQRTVRQ1 is an automotive-grade mono audio codec manufactured by Texas Instruments. It integrates a single analog-to-digital converter (ADC) and a single digital-to-analog converter (DAC). The device supports I2C and SPI control interfaces. It operates within a power supply voltage range of 3 V to 3.6 V, with a typical operating voltage of 3.3 V. The component functions reliably across a temperature range from -40°C to +125°C. Key performance metrics include a signal-to-noise ratio of 114 dB and a total harmonic distortion plus noise of -97 dB. The unit consumes 10 nA in working power current mode and is housed in a WQFN-32 package suitable for surface mount installation.

Codecs Procurement Notes

Verify the specific suffix Q1 against official Texas Instruments documentation to confirm automotive grade classification and reliability standards. Ensure the WQFN-32 package dimensions match the target PCB footprint requirements. Confirm that the I2C/SPI address configuration aligns with the system bus architecture before integration.

Codecs Selection Notes

Select this component when designing for space-constrained automotive audio applications requiring mono channel processing. The WQFN-32 package offers a compact solution compared to larger QFP or SOIC alternatives. Consider the 3V minimum supply voltage constraint when designing the power management section of the host system.
