TAC5212IRGER

Codecs Overview

The TAC5212IRGER is a high-performance stereo audio codec manufactured by Texas Instruments, designed for applications requiring superior audio fidelity and low power consumption. It integrates two analog-to-digital converters (ADCs) and two digital-to-analog converters (DACs), supporting I2S interface protocols. The device operates within a supply voltage range of 1.65 V to 3.6 V and functions reliably across an extended temperature range from -40°C to +125°C. Key performance metrics include signal-to-noise ratios of 119 dB and 120 dB. Packaged in a compact VQFN-24 format, it supports features such as digital microphone input, headset detection, and matrix mixing.

Codecs Feature Summary

• Integrates a stereo headphone amplifier with bypass mode capability for flexible output configurations.
• Supports digital microphone inputs and includes built-in mic bias circuitry.
• Features hardware-controlled matrix mixing and phase-locked loop (PLL) for precise clock management.
• Includes thermal foldback protection and PowerTune technology for enhanced system reliability.

Codecs Applications

• High-fidelity portable audio players and streaming devices
• Smart home voice assistants and smart speakers
• Automotive infotainment systems requiring wide temperature operation

Codecs Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure compatibility with required packaging options such as cut tape or reel. Confirm that the component meets RoHS compliance standards relevant to your target market regulations. Check for any recent lifecycle status updates to confirm availability and long-term supply stability before finalizing procurement plans.

Codecs Selection Notes

Select this component when a stereo codec with integrated headphone amplification is required. Ensure the host processor supports the I2S interface protocol utilized by the device. Verify that the system power budget accommodates the operating current specifications. Consider the VQFN-24 package size constraints during PCB layout design to ensure adequate thermal dissipation and mechanical fit.

Codecs Part Context

This part belongs to the TAC5212 series of audio codecs from Texas Instruments. It is distinct from other series like the TAS2521, which is a Class-D speaker amplifier, or the TAC5142, which lacks the integrated headphone amplifier found in the TAC5212. The EVM-K development kit is available for evaluating this specific codec family.

Codecs Replacement Considerations

The TAC5142IRGER is a related stereo audio codec within the same package but lacks the integrated headphone amplifier. Direct substitution requires verifying if the application relies on the internal amplifier or uses external drivers. No other direct pin-compatible substitutes are confirmed in public documentation.
