Product details

24-bit stereo codec with sigma-delta conversion

The TLV320AIC28IRGZRG4 is a low-power stereo audio codec from Texas Instruments, built around a sigma-delta modulator architecture for high-fidelity conversion. It resolves 24 b per channel, with a single ADC and two DACs supporting a stereo playback path and a mono record path. The serial data interface keeps the digital bus to a minimum — I2S or similar left-justified formats — which simplifies routing on a 2-layer board if the MCU has a dedicated audio peripheral.

The ADC delivers 90 dB SNR typical, while the DAC achieves 95 dB SNR typical. Supply rails are split: analog from 3V to 3.6V, digital from 1.65V to 1.95V. The digital rail can run directly from a 1.8V regulator, common on modern MCU boards, but the analog rail needs a clean 3.3V LDO — a shared switcher may push switching ripple into the 90 dB SNR floor.

Active production — no last-time-buy pressure

The 48-VQFN (7x7) exposed-pad package is a common footprint for audio codecs.
