TLV320AIC1106PWG4

Codecs Overview

The TLV320AIC1106PWG4 is a mono audio CODEC manufactured by Texas Instruments, housed in a TSSOP-20 surface-mount package. It features one ADC and one DAC with a resolution of 13 bits. The device supports an 8 kHz conversion rate and utilizes hardware (H/W) interface communication. Operating within a supply voltage range of 2.7 V to 3.3 V, it draws 7 mA during operation. The component functions across a temperature range from -40°C to +85°C and includes programmable gain control capabilities.

Codecs Feature Summary

• Integrates single-ended microphone input and headphone output stages for basic audio capture and playback.
• Supports dynamic channel switching between left and right DAC outputs for flexible speaker configuration.
• Enables on-the-fly digital volume control adjustments via register updates.

Codecs Applications

• Connecting microphones to single-ended inputs using TRRS jacks.
• Driving headphones or speakers connected to single-ended outputs.
• Multi-speaker setups requiring dynamic channel switching between devices.

Codecs Procurement Notes

Verify the specific suffix G4 indicates lead-free compliance and RoHS status against current manufacturer documentation. Confirm the TSSOP-20 package dimensions match your PCB footprint requirements. Ensure the 2.7 V to 3.3 V operating voltage aligns with your system power rails. Check for any obsolescence notices or lifecycle changes directly from Texas Instruments before finalizing procurement plans.

Codecs Selection Notes

Select this component when a low-channel-count solution with programmable gain is required. It suits applications needing simple hardware interface control rather than complex serial protocols like I2S or SPI. Consider the 13-bit resolution limits if higher fidelity is necessary. Verify that the mono architecture meets the signal path requirements without needing stereo separation.

Codecs Part Context

This part belongs to the TLV320AIC1106 series of PCM CODECs designed for voice and basic audio applications. It serves as a bridge between analog audio signals and digital processing units. The PWG4 designation specifies the tube packaging and environmental compliance attributes defined by Texas Instruments for this specific variant.

Codecs Replacement Considerations

Consult Texas Instruments official substitution guides for direct pin-compatible alternatives. Verify functional equivalence regarding the 13-bit resolution and 8 kHz sample rate constraints. Ensure any replacement maintains the same TSSOP-20 package outline and voltage specifications.
