UDA1380TT/N2,518

Overview

The UDA1380TT is a stereo audio coder-decoder manufactured by NXP USA Inc., housed in a TSSOP32 package. It supports a 2.4 V to 3.6 V power supply and features a 24-bit data path for both ADC and DAC sections. The device includes a selectable L3-bus or I2C-bus control interface, with digital inputs tolerant to 5 V at 2.7 V to 3.6 V supply voltages. It accommodates sample frequencies from 8 kHz to 55 kHz for the ADC and up to 100 kHz for the DAC. Key specifications include a typical signal-to-noise ratio of 97 dB for both conversion directions and integrated headphone driver capabilities.

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 interfaces with flexible clocking via SYSCLK or WSPLL.
• Includes digital sound processing features such as volume control, mute, de-emphasis, bass boost, and treble adjustment accessible via bus interface.
• Features a built-in headphone driver capable of driving 16 Ω loads without external DC decoupling capacitors, equipped with short-circuit protection.

Applications

• Mini-Disc (MD) players
• Compact-Disc (CD) players
• MP3 players

Procurement Notes

Verify the specific ordering suffix TT against the datasheet to confirm the TSSOP32 package type. Confirm that the component status aligns with historical availability requirements, as this series may be discontinued. Ensure compatibility with existing board layouts designed for the 32-lead thin shrink small outline package dimensions.

Selection Notes

Select this component when designing portable audio systems requiring integrated analog front-end amplification and digital filtering. Consider the dual clock domain capability if asynchronous ADC and DAC operation is required. Verify that the system can accommodate the specific pinout configuration of the TSSOP32 package compared to alternative HVQFN packages.

Part Context

The UDA1380TT belongs to the UDA1380 family of stereo audio coder-decoders designed for consumer electronics. It shares identical functional specifications with the UDA1380HN variant, differing only in the physical packaging. This family targets applications needing high-quality audio conversion with minimal external components.
