That sample rate means it captures a full 12-bit word every microsecond — fast enough to digitize a 500 kHz analog signal with Nyquist margin, or to interleave multiple channels in a multiplexed front-end without dropping edges. The input multiplexer accepts four differential or eight single-ended channels, and also supports pseudo-differential mode — so a single part handles a ratiometric bridge sensor (differential), a bank of thermocouples (single-ended), or a mix of both without an external mux. ## Supply rails and temperature range — where this ADC lives The reference is external (not on-chip), so the full-scale range and noise floor are set by the reference voltage you choose — a low-drift 2.5 V reference gives a 2.5 V full-scale input; a 4.096 V reference gives a 4.096 V range, limited by the 3.6 V analog supply ceiling. ## Package, interface, and what it connects to The SPI/DSP serial interface connects directly to most MCU SPI peripherals or a DSP's serial port; the 1 Msps throughput at 12 bits means the serial clock runs at about 16 MHz minimum to keep the output register from stalling the next conversion. ## Lifecycle and sourcing — active, no cross-reference needed No pin-compatible second-source is listed; the part is a single-source ADC in its class, so a BOM hedge would require a board-spin to a different pinout.","metaTitle":"MAX11325ATJ+ ADC, 12-Bit SAR, 1 Msps, 32-TQFN","metaDescription":"MAX11325ATJ+ 12-bit SAR ADC, 1 Msps, 4/8-channel differential/pseudo-differential/single-ended input, SPI/DSP interface, 32-TQFN, -40 to +125°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"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":"4, 8","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":"$8.8","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$8.80000","currency":"USD"},{"qty":10,"price":"$7.94800","currency":"USD"},{"qty":25,"price":"$7.57800","currency":"USD"},{"qty":100,"price":"$6.57990","currency":"USD"},{"qty":250,"price":"$6.28424","currency":"USD"},{"qty":500,"price":"$5.72972","currency":"USD"},{"qty":1000,"price":"$4.99041","currency":"USD"}]},"links":{"datasheetUrl":null,"sourceUrl":null},"ai":{"faq":[{"question":"What input types does the MAX11325ATJ+ support?","answer":"It supports differential, pseudo-differential, and single-ended inputs, configurable through the on-chip multiplexer.
