It accepts input sample rates from 4 kHz to 216 kHz. The device operates from a 3 V to 3.6 V supply and is specified over the industrial temperature range of -40°C to 85°C. It comes in a 48-pin TQFP package (7x7 mm body) with a surface-mount footprint, suitable for professional audio equipment, broadcast consoles, digital mixing desks, and audio interface cards that require asynchronous sample rate conversion between digital audio sources. ## Sample rate range and what it means for the signal chain The 4 kHz to 216 kHz input range covers narrowband voice through professional studio rates. ## Control interface and integration Dual I²C and SPI support means the SRC4382IPFB can drop into designs where the host already has one bus type without adding a protocol translator. I²C is the usual choice when only a few registers are accessed at startup; SPI gives faster register readback for monitoring conversion status or debugging. The interface selection is typically strapped with a hardware pin, so the BOM sees no extra glue logic. ## Lifecycle and sourcing It is ROHS3 compliant.","metaTitle":"SRC4382IPFB Sample Rate Converter, 4kHz-216kHz, 48-TQFP","metaDescription":"Texas Instruments SRC4382IPFB stereo sample rate converter with I²C/SPI interface, 3V-3.6V supply, -40°C to 85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Package":"Tray","Function":"Sample Rate Converter","Interface":"I²C, SPI","Applications":"Digital Audio Interfacing","Mounting Type":"Surface Mount","Package / Case":"48-TQFP","Specifications":"4kHz ~ 216kHz","lifecycle_stage":"eol_hot","Voltage - Supply":"3V ~ 3.6V","Number of Channels":"2","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"48-TQFP (7x7)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$15.29","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$15.29000","currency":"USD"},{"qty":10,"price":"$14.05100","currency":"USD"},{"qty":25,"price":"$13.46880","currency":"USD"},{"qty":80,"price":"$11.86725","currency":"USD"},{"qty":250,"price":"$11.28476","currency":"USD"},{"qty":500,"price":"$10.55672","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/d0a6e5d83d5bc02a01ab0ffd15d6bea7.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the difference between SRC4382IPFB and SRC4382IPFBR?","answer":"The SRC4382IPFB ships in a Tray, while the SRC4382IPFBR variant ships in Tape & Reel.
