Product details

Stereo audio ADC for line-level capture

The Texas Instruments PCM1803ADBR is a stereo audio ADC that digitizes two channels at 24-bit resolution and a 96 kHz sampling rate.

The PCM1803ADBR has separate analog and digital supply pins. The analog supply accepts 4.5 V to 5.5 V, and the digital supply runs from 2.7 V to 3.6 V.

The part comes in a 20-pin SSOP package (0.209" body width, 5.30 mm), which is a standard surface-mount footprint.

It is ROHS3 compliant (lead-free). For BOM planning, there is no LTB risk on the horizon. If you are qualifying a new design, this part is safe to specify for production.

Frequently asked questions

Is the PCM1803ADBR compatible with 3.3 V logic?

Yes. The digital supply (VDD) range is 2.7 V to 3.6 V, so the serial audio interface operates at 3.3 V logic levels without external level shifters.
