SGTL5000XNLA3R2

Codecs Overview

The SGTL5000XNLA3R2 is a low-power stereo audio codec with an integrated headphone amplifier, manufactured by NXP Semiconductors. It provides a comprehensive audio solution for portable products requiring line-in, mic-in, line-out, headphone-out, and digital I/O. The device operates within a supply voltage range of 1.62 V to 3.6 V and supports sampling frequencies from 8 kHz to 96 kHz. Key performance metrics include an ADC SNR of 85 dB at 1.8 V and 90 dB at 3.3 V, alongside a DAC SNR of 100 dB. It features a capless headphone design, programmable microphone gain, and integrated digital audio processing capabilities such as surround sound and bass enhancement.

Codecs Feature Summary

• Capless headphone output design that eliminates the need for external coupling capacitors, reducing overall system cost and board space.
• Integrated Phase-Locked Loop (PLL) allowing flexible clocking options using system clocks between 8.0 MHz and 27 MHz.
• Built-in digital audio processing blocks including NXP Surround, Bass Enhancement, and parametric/graphic equalizers.
• Programmable microphone bias and gain stages supporting direct connection of MEMS or electret microphones.

Codecs Applications

• Portable media players and navigation devices
• Smartphones and tablets
• Medical equipment and exercise equipment
• Consumer audio equipment

Codecs Procurement Notes

Verify the specific ordering suffix R2 indicates tape-and-reel packaging when sourcing components. Confirm the package type corresponds to the 20-pin sawn QFN variant specified for this part number. Ensure compatibility with the required operating temperature range of -40°C to +85°C for the intended application environment.

Codecs Selection Notes

Select the SGTL5000XNLA3R2 for designs prioritizing ultra-low power consumption in portable electronics. This 20-pin QFN package is suitable for applications with strict footprint constraints compared to the 32-pin variants. Consider the internal PLL functionality if the host processor lacks a precise audio master clock source.

Codecs Part Context

This component belongs to the SGTL5000 family of low-power stereo codecs. The XNLA3R2 designation specifically identifies the 20-pin sawn QFN package version with reel packaging. It shares the same core architecture and electrical specifications as the 32-pin QFN variants, differing primarily in physical dimensions and pin count.

Codecs Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. The SGTL5000XNAA3/R2 (32-pin) is a pin-compatible alternative but requires verification of package differences.
