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.","metaTitle":"TLV320AIC28IRGZRG4 Stereo Audio Codec – TI, 24-bit, Active","metaDescription":"Texas Instruments TLV320AIC28IRGZRG4 – Stereo Audio codec, 24 b resolution, 90/95 dB SNR, -40°C to 85°C, 48-VQFN.
