SGTL5000
Overview
The SGTL5000 is a low-power stereo audio codec that includes a headphone amplifier and an internal PLL. It is designed to provide a complete audio solution for portable devices, featuring high-quality audio processing with minimal external components. It supports multiple digital interfaces including I2S, I2C, and SPI for flexible system integration.
Why Choose This Part
This codec features a capless headphone design that reduces the physical footprint and BOM cost by eliminating bulky output coupling capacitors. Its internal PLL allows for flexible clocking from various system frequencies, and its low power consumption (under 12 mW during 3.3V playback) makes it ideal for battery-operated designs.
Applications
Key Specifications
Getting Started
Engineers often start with the PJRC Teensy Audio Shield, which provides a ready-made implementation of the SGTL5000 with an extensive Arduino-compatible library. Hardware design requires attention to the 20-UFQFN package thermal pad and dual power supplies, with digital logic typically operating at 1.8V or 3.3V and analog sections up to 3.6V.
