SRC4184IPAGT

Audio Special Purpose Overview

The SRC4184IPAGT is a dual-channel audio sample rate converter manufactured by Texas Instruments. It supports input sampling rates up to 216 kHz and output rates up to 192 kHz, enabling flexible clock domain conversion for digital audio systems. The device features a dynamic range of 139 dB and a THD+N of -125 dBFS, ensuring high-fidelity signal processing. It operates on a single 3.3 V supply with low power consumption. Communication is managed via an I2C interface for configuration. The component is housed in a 48-pin TQFP package suitable for surface-mount assembly.

Audio Special Purpose Procurement Notes

Verify the specific suffix IPAGT against the manufacturer datasheet to confirm the tape-and-reel packaging quantity and moisture sensitivity level. Ensure the ordering information matches the exact pin count and thermal pad requirements specified in the official package drawing to avoid assembly discrepancies.

Audio Special Purpose Selection Notes

Select this component when dual-channel conversion between asynchronous audio clocks is required. Compare the 139 dB dynamic range against system noise floor requirements. Verify that the 3.3 V operating voltage aligns with the target system's power rails and that the I2C interface is compatible with the host controller.

Audio Special Purpose Part Context

This part belongs to the SRC41xx series of audio sample rate converters from Texas Instruments. It is designed to replace older discrete solutions or simpler converters by providing integrated filtering and resampling capabilities in a compact form factor, targeting high-end consumer and professional audio markets.

Audio Special Purpose Replacement Considerations

Check the SRC4190 or SRC4192 for alternative channel counts or package options. Verify pin-to-pin compatibility if substituting within the same family. Confirm that the replacement part supports the required 216 kHz input rate and 139 dB dynamic range specifications.
