16-bit sigma-delta CODEC for general-purpose audio paths
The sigma-delta architecture delivers 87 dB SNR on the ADC path and 90 dB on the DAC path, with 82 dB dynamic range on both sides — figures that suit line-level audio capture and playback in consumer and commercial indoor gear. The serial data interface keeps the pin count manageable and pairs naturally with I2S or similar serial audio links. Supply flexibility — 3 V to 5.5 V on both analog and digital rails — simplifies rail assignment in mixed-voltage designs.
This part qualifies for new-design insertion and ongoing production without a PCN watch for discontinuation. For dual-sourcing resilience, TI's CODEC family includes pin-compatible siblings with similar serial interfaces — verify the exact alternate against your host controller's serial protocol and supply voltage.
48-TQFP footprint and supply rails
The 48-TQFP (7x7 mm) package is a surface-mount fine-pitch quad flat pack. Both analog and digital supply pins accept 3 V to 5.5 V.
