UDA1380HN/N2,118

Overview

The UDA1380HN/N2,118 is a stereo audio coder-decoder manufactured by NXP USA Inc., designed for Mini-Disc, CD, and MP3 applications. It features a 24-bit data path for both ADC and DAC sections with typical signal-to-noise ratios of 97 dB for both conversion directions. The device operates on a single 2.4 V to 3.6 V supply and supports sampling frequencies from 8 to 55 kHz for recording and 8 to 100 kHz for playback. It includes integrated headphone drivers capable of driving 16 Ω loads and offers digital tone control, de-emphasis, and volume management via L3-bus or I2C-bus interfaces.

Feature Summary

• Integrated stereo line input with programmable gain amplifier and mono microphone input featuring low noise amplifier and variable gain amplifier.
• Supports multiple digital audio formats including I2S, MSB-justified, and LSB-justified with selectable master or slave clock modes.
• Includes digital sound processing features such as bass boost, treble adjustment, de-emphasis, and soft mute functions.
• Features independent power management controls for ADC, DAC, PLL, and headphone driver blocks to optimize energy consumption.

Applications

• Mini-Disc players
• Compact-Disc players
• MP3 players

Procurement Notes

Verify the component status as discontinued based on distributor records. Confirm package type HVQFN32 matches design requirements. Ensure compatibility with existing L3-bus or I2C-bus control logic. Review thermal characteristics for surface mount assembly. Validate RoHS compliance documentation prior to integration.

Selection Notes

Select this component for portable audio systems requiring high-fidelity stereo conversion within a compact footprint. Consider the integrated headphone driver capability when designing output stages without external coupling capacitors. Evaluate the available digital filtering options for specific audio enhancement needs. Verify supply voltage ranges align with system battery specifications.

Part Context

This part belongs to the UDA1380 family of stereo audio coder-decoders. It is functionally identical to the TSSOP32 variant (UDA1380TT) but utilizes an HVQFN32 package. The device integrates analog front-ends, digital filters, and control interfaces into a single solution for consumer audio electronics.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Designers should review the superseded data sheet date and contact the manufacturer for current lifecycle recommendations.
