This is a two-row gull-wing lead form; the 0.209\" width keeps the analog and digital supply traces short on a two-layer board, but a ground plane under the package helps isolate the 24-bit conversion from digital switching noise. ## Supply rails and analog/digital separation The voltage supply source is listed as both analog and digital — meaning the ADC has separate AVDD and DVDD pins. The 5 V analog rail sets the full-scale input range; the 3.3 V digital rail mates directly with a 3.3 V serial host without a level shifter. The 2-channel serial data interface (likely I²S or left-justified) carries the 24-bit word at up to 96 kHz sample rate per channel. This covers outdoor telecom cabinets, factory-floor audio capture, and automotive cabin (non-engine-bay) applications. The 24-bit resolution at 96 kHz sampling is typical for professional-grade line-level inputs; the dynamic range is limited by the analog supply noise floor, not the converter itself.","metaTitle":"PCM1803ADB Texas Instruments ADC, Audio, 24-bit, 96 kHz","metaDescription":"PCM1803ADB Texas Instruments ADC, Audio, 24-bit, 96 kHz sampling, 2-channel, serial interface, 20-SSOP package.
