The dual-supply architecture separates the analog rail (3V to 3.6V) from the digital I/O rail (1.65V to 1.95V), so it can interface directly with a 1.8V logic domain without an external level shifter. ## Dual supply rails and 1.8V digital compatibility The digital supply range of 1.65V to 1.95V means the PCM1820IRTER is compatible with a 1.8V digital supply — a common I/O voltage for modern SoCs and FPGAs. The analog supply runs from 3V to 3.6V, typically 3.3V. This split-rail design keeps the analog performance clean while matching the digital interface voltage of the host processor. ## 20-WFQFN with exposed pad — layout notes The package is a 20-WFQFN with an exposed pad (3x3 mm body, supplier device package 20-WQFN). Surface-mount only. The small footprint suits space-constrained audio capture boards.","metaTitle":"PCM1820IRTER Stereo Audio ADC, 32-Bit 192 kHz, Burr-Brown","metaDescription":"TI Burr-Brown PCM1820IRTER stereo audio ADC: 32-bit, 192 kHz sampling, I²S/TDM interface, -40°C to 125°C.","metaKeywords":null},"attributes":{"series":"Burr-Brown™","packageCase":null,"mountingType":null,"rohsStatus":"Not applicable","productStatus":"Active","categoryPath":["Logic ICs"],"specifications":{"Type":"ADC, Audio","Series":"Burr-Brown™","Package":"Tape & Reel (TR); Cut Tape (CT)","Mounting Type":"Surface Mount","Data Interface":"I²S, TDM","Package / Case":"20-WFQFN Exposed Pad","lifecycle_stage":"eol_hot","Voltage - Supply":"3V ~ 3.6V, 1.65V ~ 1.95V","Number of Channels":"2","Operating Temperature":"-40°C ~ 125°C (TA)","Voltage Supply Source":"Analog and Digital","Supplier Device Package":"20-WQFN (3x3)","Sampling Rate (Per Second)":"8k ~ 192k"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.16","priceTiers":[{"qty":1,"price":"$4.16000","currency":"USD"},{"qty":10,"price":"$3.74000","currency":"USD"},{"qty":25,"price":"$3.53600","currency":"USD"},{"qty":100,"price":"$3.06450","currency":"USD"},{"qty":250,"price":"$2.90740","currency":"USD"},{"qty":500,"price":"$2.60878","currency":"USD"},{"qty":1000,"price":"$2.20018","currency":"USD"},{"qty":3000,"price":"$1.65360","currency":"USD"},{"qty":6000,"price":"$1.59144","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/097de4ef7d99368974734b254f8c13dd.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/PCM1820IRTER/alternatives.json"},"ai":{"faq":[{"question":"Is PCM1820IRTER compatible with a 1.8V digital supply?","answer":"Yes.
