It operates from separate analog (1.8V) and digital (3.3V) supply rails, keeping the analog audio path isolated from the digital switching noise. The digital interface is I²C, so the host microcontroller programs the volume, mute, and power-down registers over a two-wire bus — no extra address lines needed beyond the serial clock and data. The 24-bit resolution and 96 kHz rate cover the full audio band with headroom for 48 kHz or 44.1 kHz base rates. ## Package, footprint, and temperature grade The dual supply sources (analog and digital) mean the analog rail can be a clean 1.8V LDO while the digital rail runs from a noisier 3.3V supply — the internal PSRR handles the cross-talk if the layout keeps the analog return path separate. ## Lifecycle and compliance The ROHS3 compliance covers the full substance restriction, including the four phthalates, so it passes EU and UKCA requirements without an exemption expiry to track.","metaTitle":"TLV320DAC32IRHBT DAC, 24-bit, 96k, I2C, 32-VQFN","metaDescription":"Texas Instruments TLV320DAC32IRHBT, 24-bit 96k stereo DAC with I2C serial interface in 32-VQFN (5x5) package.
