It accepts differential, pseudo-differential, or single-ended inputs through an internal multiplexer feeding a sample-and-hold stage, all controlled via a SPI or DSP serial interface. The single 2.35 V to 3.6 V supply powers both the analog and digital sections, which simplifies rail planning — no separate AVDD and DVDD regulators needed. An external reference sets the full-scale range, so the designer picks the voltage that matches the sensor or signal conditioner output. ## Input flexibility and routing The input mux supports 8, 15, or 16 channels depending on the configuration — differential pairs, pseudo-differential with a common return, or single-ended. That range covers applications from multi-channel data acquisition on a PLC analog input module to monitoring thermocouple or RTD signals in a temperature controller. The 1:1 S/H-to-ADC ratio means each conversion samples a fresh input; there is no pipeline delay to budget for. ## Temperature grade and environment Rated for -40°C to +125°C, this ADC suits industrial and automotive environments. The 32-TQFN (5x5 mm) package fits space-constrained PCBs. ## Lifecycle and sourcing The MAX11328ATJ+ is listed as Active on Maxim's product status. No last-time-buy or end-of-life notice is in effect, so it remains a safe choice for new designs and production BOMs. ROHS3 compliant.","metaTitle":"MAX11328ATJ+ 12-bit SAR ADC, 1 Msps, SPI, -40/+125°C","metaDescription":"MAX11328ATJ+ 12-bit SAR ADC, 1 Msps sampling rate, differential/pseudo-differential/single-ended inputs, SPI/DSP interface, -40°C to +125°C, 32-TQFN.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Package":"Tube","Input Type":"Differential, Pseudo-Differential, Single Ended","Architecture":"SAR","Configuration":"MUX-S/H-ADC","Mounting Type":"Surface Mount","Data Interface":"SPI, DSP","Number of Bits":"12","Package / Case":"32-WFQFN Exposed Pad","Reference Type":"External","Ratio - S/H:ADC":"1:1","lifecycle_stage":"eol_hot","Number of Inputs":"8, 15, 16","Operating Temperature":"-40°C ~ 125°C","Supplier Device Package":"32-TQFN (5x5)","Number of A/D Converters":"1","Voltage - Supply, Analog":"2.35V ~ 3.6V","Voltage - Supply, Digital":"2.35V ~ 3.6V","Sampling Rate (Per Second)":"1M"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$11.03","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$11.03000","currency":"USD"},{"qty":10,"price":"$9.96700","currency":"USD"},{"qty":25,"price":"$9.50360","currency":"USD"},{"qty":100,"price":"$8.25190","currency":"USD"},{"qty":250,"price":"$7.88104","currency":"USD"},{"qty":500,"price":"$7.18564","currency":"USD"},{"qty":1000,"price":"$6.25846","currency":"USD"}]},"links":{"datasheetUrl":"https://datasheets.maximintegrated.com/en/ds/MAX11321-MAX11328.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Can MAX11328ATJ+ interface with SPI?","answer":"Yes, the data interface supports both SPI and DSP serial protocols, making it compatible with most microcontrollers and DSPs."},{"question":"What input types does MAX11328ATJ+ support?","answer":"It accepts differential, pseudo-differential, and single-ended inputs, configurable through the internal multiplexer."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/MAX11328ATJ","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/MAX11328ATJ when reusing this data.
