TAS3103DBTRG4

Audio Special Purpose Overview

The Texas Instruments TAS3103DBTRG4 is a fully configurable digital audio processor housed in a 38-pin TSSOP package. It features a 48-bit data path and supports sample rates from 8 kHz to 96 kHz. The device includes four serial audio input channels and three output channels, utilizing a single 3.3-V power supply with 1.8-V core logic. It provides three independent monaural processing channels equipped with programmable parametric EQ, soft volume control, and dynamic range compression. Configuration is managed via a serial I2C interface.

Audio Special Purpose Feature Summary

• Four Serial Audio Input Channels and Three Output Channels
• Three Independent Monaural Processing Channels with Parametric EQ
• Programmable Soft Volume Control (24 dB to -∞ dB)
• Dual Threshold Dynamic Range Compression/Expansion

Audio Special Purpose Applications

• Digital Audio Interfacing

Audio Special Purpose Procurement Notes

Verify the G4 suffix indicates lead-free compliance and RoHS adherence per manufacturer specifications. Confirm the 38-TSSOP package dimensions match the design footprint. Ensure the operating temperature range of 0°C to 70°C aligns with the target environment requirements before finalizing procurement.

Audio Special Purpose Selection Notes

Select this component for applications requiring flexible digital audio processing with minimal external glue logic. The device supports multiple serial data formats including I2S and TDM. Verify that the system clock architecture can accommodate the internal DPLL or bypass modes required for the specific audio sample rate.

Audio Special Purpose Part Context

The TAS3103 belongs to the Texas Instruments digital audio solutions family. It is designed to replace discrete audio processing circuits by integrating mixing, filtering, and effects into a single low-power IC. The DBT variant specifically denotes the plastic 38-pin TSSOP package suitable for surface mount assembly.

Audio Special Purpose Replacement Considerations

The TAS3103DBT is the standard non-reflow-compatible equivalent. For automotive applications, verify if the Q1 graded variants are required instead.
