It samples at 115k samples per second over the SPI bus, accepting either differential or single-ended inputs through its 4 or 8 input channels (configured as 4 differential or 8 single-ended). The internal PGA lets you amplify small sensor signals before conversion, saving an external op-amp stage and its associated BOM cost and board area. ## 115k SPS at 16 bits — where the speed fits At 115k samples per second and 16-bit resolution, this ADC sits in the sweet spot for industrial data-acquisition systems that need moderate throughput with real dynamic range. A 16-bit conversion at 115k SPS gives an LSB size of about 76 µV on a 5 V reference — enough to resolve thermocouple, strain-gauge, or pressure-sensor outputs without external gain. The SAR architecture means no pipeline delay: the conversion result for a given sample is available on the next SPI transaction, which simplifies real-time control loops. ## Differential or single-ended — 4 or 8 channels The input multiplexer gives you a choice: four differential pairs or eight single-ended inputs. Differential mode rejects common-mode noise on long sensor leads, which matters in factory-floor or motor-drive environments where ground loops are common. Single-ended mode doubles the channel count for monitoring multiple DC voltages or logic-level signals. The on-chip PGA provides selectable gain, letting you match the input range to the sensor output without external resistors. ## 5 V supply, SPI interface, industrial temperature range Both analog and digital supplies run from a single 5 V rail, simplifying power-tree design. The SPI data interface uses four wires (SCLK, DIN, DOUT, CS) and is compatible with most microcontrollers and DSPs — no parallel bus or address decoding needed. The -40°C to 85°C operating temperature range covers industrial control cabinets, outdoor telecom enclosures, and automotive cabin-adjacent modules. The 24-TSSOP package with 0.173-inch body width fits on compact PCB layouts. ## Active lifecycle — no last-time-buy pressure ROHS3 compliant per, so it meets the latest EU restriction directives. For a BOM line that needs a 16-bit SAR ADC with PGA and SPI, this part can be specified into new designs without worrying about a looming last-time-buy window.","metaTitle":"MAX1302AEUG+ 16-bit SAR ADC, 115k SPS, SPI, 24-TSSOP","metaDescription":"Maxim MAX1302AEUG+ 16-bit SAR ADC with 115k sampling rate, SPI interface, PGA, 4/8 differential/single-ended inputs, -40°C to 85°C, 24-TSSOP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["DC-DC Power Modules"],"specifications":{"Package":"Tube","Features":"PGA","Input Type":"Differential, Single Ended","Architecture":"SAR","Configuration":"MUX-PGA-S/H-ADC","Mounting Type":"Surface Mount","Data Interface":"SPI","Number of Bits":"16","Package / Case":"24-TSSOP (0.173\\\", 4.40mm Width)","Reference Type":"External, Internal","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":"5V","Sampling Rate (Per Second)":"115k"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$23.94","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$23.94000","currency":"USD"},{"qty":10,"price":"$22.07700","currency":"USD"},{"qty":25,"price":"$21.08480","currency":"USD"},{"qty":100,"price":"$18.85230","currency":"USD"},{"qty":250,"price":"$17.98408","currency":"USD"},{"qty":500,"price":"$17.11586","currency":"USD"}]},"links":{"datasheetUrl":"https://datasheets.maximintegrated.com/en/ds/MAX1302.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is MAX1302AEUG+ compatible with SPI interface?","answer":"Yes, the data interface is SPI.
