The internal multiplexer selects between four pseudo-differential inputs or eight single-ended inputs, giving the board designer one device that covers both input architectures without an external mux. The 200 kSPS throughput suits medium-speed data-acquisition chains — think multi-channel sensor monitoring, motor-phase current feedback, or battery-stack voltage scanning — where 12-bit resolution is enough and the per-channel rate stays below 50 kHz per channel when all eight inputs are scanned round-robin. ## Supply rails and interface — separate analog and digital domains The external reference input (REF) sets the full-scale range — no internal bandgap reference, so the system reference noise and drift directly affect the ADC's INL and DNL. The SPI data interface uses a standard 4-wire (CS, SCLK, SDI, SDO) protocol. The conversion is initiated by the CS falling edge; the result is shifted out on SDO during the next conversion cycle. The digital supply range means the interface works with 3.3 V MCUs like the STM32 or 5 V legacy controllers without a translator. ## Temperature grade and package — industrial range in a 24-TSSOP Shipped in tube packaging, so it arrives in an anti-static tube suitable for manual pick-and-place or small-batch assembly. ROHS3 compliant — no restricted substances and no exemption expiry to track on the BOM compliance sheet.","metaTitle":"TLC2578IPW 12-bit SAR ADC, 200 kSPS, 8-ch MUX, 24-TSSOP","metaDescription":"Texas Instruments TLC2578IPW 12-bit SAR ADC, 200 kSPS sampling rate, 4/8-channel input mux, pseudo-differential/single-ended, SPI interface, -40 to 85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Package":"Tube","Input Type":"Pseudo-Differential, Single Ended","Architecture":"SAR","Configuration":"MUX-S/H-ADC","Mounting Type":"Surface Mount","Data Interface":"SPI","Number of Bits":"12","Package / Case":"24-TSSOP (0.173\\\", 4.40mm Width)","Reference Type":"External","Ratio - S/H:ADC":"1:1","lifecycle_stage":"eol_hot","Number of Inputs":"4, 8","Operating Temperature":"-40°C ~ 85°C","Supplier Device Package":"24-TSSOP","Number of A/D Converters":"1","Voltage - Supply, Analog":"5V","Voltage - Supply, Digital":"2.7V ~ 5.5V","Sampling Rate (Per Second)":"200k"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$19.68","priceTiers":[{"qty":1,"price":"$19.68000","currency":"USD"},{"qty":10,"price":"$18.09100","currency":"USD"},{"qty":25,"price":"$17.34120","currency":"USD"},{"qty":100,"price":"$15.27890","currency":"USD"},{"qty":250,"price":"$14.52904","currency":"USD"},{"qty":500,"price":"$13.59170","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/b17756e8d2b4176a645ff33d33277ad4.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TLC2578IPW/alternatives.json"},"ai":{"faq":[{"question":"What is the closest functional second-source to the TLC2578IPW?","answer":"The ADC124S021CIMM/NOPB is a 12-bit SAR ADC at the same 200 kSPS sampling rate, but it is single-ended only (no pseudo-differential mode), has four inputs (not eight), and uses the supply as its reference instead of an external reference pin. It is not a pin-to-pin drop-in — the package is different (10-MSOP vs 24-TSSOP) and the interface is SPI/DSP rather than pure SPI. For a design that already uses the TLC2578IPW, a board spin would be required."},{"question":"What is the TLC2578IPW's input type and how many channels does it support?","answer":"The ADC supports both pseudo-differential and single-ended inputs, selectable via the internal multiplexer. In pseudo-differential mode it has four input channels; in single-ended mode it has eight channels. The conversion result is 12 bits at up to 200 kSPS."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TLC2578IPW","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TLC2578IPW when reusing this data.
