TLV320AIC3107IRSBR

Codecs Overview

The Texas Instruments TLV320AIC3107IRSBR is a low-power stereo audio codec featuring an integrated single-ended headphone amplifier and a mono Class-D speaker driver. It supports digital audio resolutions of 16, 20, 24, and 32 bits with sampling rates from 8 kHz to 96 kHz. The device achieves a signal-to-noise ratio of 97 dBA for the DAC and 92 dBA for the ADC. Power consumption reaches as low as 15 mW during stereo playback at 48 kHz using a 3.3 V analog supply. It includes programmable PLLs, automatic gain control, and multiple input/output configurations in a 40-pin QFN or 42-pin DSBGA package.

Codecs Feature Summary

• Integrated mono Class-D BTL speaker amplifier capable of driving 8-ohm loads
• Flexible power management with ultra-low power modes and passive analog bypass
• Programmable audio processing including 3D, bass/treble effects, and equalization

Codecs Applications

• Mobile phones and smartphones
• Portable media players
• Digital cameras
• General portable audio equipment

Codecs Procurement Notes

Verify the suffix IRSBR corresponds to the specific reel packaging and temperature grade required for your design. Confirm the component matches the 40-QFN or 42-DSGA footprint specifications in the official datasheet before finalizing procurement orders.

Codecs Selection Notes

Select this model when a combined headphone and speaker solution is needed to reduce board space. Ensure the system design accommodates the 2.7V to 5.5V supply range for the speaker amplifier and the specific digital I/O voltage requirements. Verify that the available clocking options via the programmable PLL meet the interface timing constraints.

Codecs Part Context

This component belongs to the TLV320AIC310x family of low-power audio codecs designed for battery-operated devices. It shares core architecture with other models in the series but offers specific integration of a Class-D amplifier, distinguishing it from variants that may only include line-level outputs.

Codecs Replacement Considerations

Check for pin-compatible alternatives within the same TI family if supply constraints exist. Ensure any substitute maintains the required Class-D output capability and similar power consumption profiles for direct replacement.
