TLV320AIC3106IRGZR

Texas Instruments TLV320AIC3106IRGZR Low-Power Stereo Audio CODEC (48‑VQFN)

The Texas Instruments TLV320AIC3106IRGZR is a low-power, stereo audio codec tailored for portable, embedded, and industrial audio designs that need rich analog I/O, a built-in headphone amplifier, and space-efficient packaging. Part of TI’s TLV320AIC3106 series, this device integrates 10 analog inputs and 7 analog outputs alongside enhanced digital effects, enabling flexible signal routing and compact system designs without external amplifiers for headphones.

Engineers, buyers, and sourcing managers will appreciate that TLV320AIC3106IRGZR is supplied in the RGZR ordering code—meaning the 48-pin VQFN (RGZ) package delivered in tape-and-reel for high-volume, automated assembly. With an industrial operating temperature range of -40°C to +85°C and surface-mount readiness, it fits comfortably into robust, production-grade designs.

What the TLV320AIC3106IRGZR Is

The TLV320AIC3106IRGZR is a stereo audio codec (ADC + DAC) from Texas Instruments offering a balanced blend of analog flexibility and low-power operation. It is designed to convert between analog and digital audio signals, providing both capture (via its ADC path) and playback (via its DAC path) while simplifying the bill of materials through an integrated headphone amplifier and configurable analog inputs/outputs.

Key use cases include handheld devices, battery-operated instruments, embedded panels with voice or audio feedback, and industrial equipment that requires reliable stereo capture and playback within constrained power and board-space budgets.

System Design Considerations

While many detailed parameters are application-specific and should be confirmed in the datasheet, the following general considerations can streamline your design process:

Power budgeting: Use the device’s low-power profile to meet battery life targets; cross-check standby and active-mode consumption in the datasheet for precise calculations. Not specified in datasheet within this summary.
Clocking and synchronization: Align the codec’s audio clocks with your host processor’s audio interface. Exact clocking capabilities are not specified in datasheet here; refer to TI documentation.
Microphone and line inputs: The TLV320AIC3106IRGZR provides 10 analog inputs. Review input impedance, biasing, and gain options in the datasheet to optimize noise performance. Not specified in datasheet in this summary.
Headphone drive: The integrated amplifier simplifies output stage design. Validate load impedance, output power, and protection mechanisms against system requirements. Not specified in datasheet in this summary.
EMI/EMC: Keep analog paths short and shielded where possible; isolate high-current digital return paths.
