SRC4382IPFBT

Audio Special Purpose Overview

The SRC4382IPFBT is a two-channel asynchronous sample rate converter (SRC) manufactured by Texas Instruments. It integrates digital audio interface receivers and transmitters, supporting standard formats such as I2S, Left-Justified, and TDM. The device converts input sampling rates from 8 kHz to 192 kHz with high precision. Key electrical specifications include a dynamic range of 116 dB and a total harmonic distortion plus noise (THD+N) of -105 dB. It operates on a single 3.3 V supply and is housed in an 80-pin LQFP package.

Audio Special Purpose Feature Summary

• Two-channel asynchronous sample rate conversion supporting 8 kHz to 192 kHz input and output rates
• Integrated digital audio interface receiver and transmitter compatible with I2S, Left-Justified, and TDM formats
• High-performance audio metrics including 116 dB dynamic range and -105 dB THD+N
• Supports up to 24-bit resolution for digital audio processing

Audio Special Purpose Applications

• Professional audio mixing consoles requiring multi-rate synchronization
• Broadcasting equipment for format conversion between different sampling standards
• Digital audio workstations and recording interfaces
• Home theater systems connecting sources with varying clock rates

Audio Special Purpose Part Context

The SRC4382 belongs to the Burr-Brown audio IC family acquired by Texas Instruments. It is functionally similar to the SRC4392 but offers specific integration levels for digital interfaces. The IPFBT suffix indicates the 80-pin LQFP package and tape-and-reel shipping configuration.

Audio Special Purpose Replacement Considerations

The SRC4392 is a documented similar part within the same product family, offering comparable two-channel asynchronous conversion capabilities. Verification of pin compatibility and specific feature requirements is necessary before substitution.
