The MUX-S/H-ADC architecture means the single converter is shared across all channels, so the per-channel throughput drops as you enable more inputs — at 8 single-ended channels, each sees roughly 6.25k SPS. Both analog and digital supply rails are 5V, eliminating the need for a separate I/O voltage rail when interfacing with a 5V-tolerant SPI bus. The SPI data interface keeps the pin count low and the layout simple — four wires (SCLK, DIN, DOUT, CS) handle all communication. ## Package and board-fit — 20-SSOP with 0.209-inch body width The 20-SSOP footprint is common and well-supported by standard land patterns — no exotic pad geometry required. The 1:1 S/H-to-ADC ratio means the sample-and-hold capacitor is dedicated to the active channel, so there is no charge-sharing penalty when switching between inputs — the acquisition time is consistent regardless of which MUX channel is selected.","metaTitle":"Analog Devices MAX1112EAP+ 8-bit SAR ADC, 50k SPS, 20-SSOP","metaDescription":"Analog Devices MAX1112EAP+ 8-bit SAR ADC. 50k samples/sec, 4/8 input channels, differential/single-ended, SPI interface, 5V supply, -40 to +85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["DC-DC Power Modules"],"specifications":{"Package":"Tube","Input Type":"Differential, Single Ended","Architecture":"SAR","Configuration":"MUX-S/H-ADC","Mounting Type":"Surface Mount","Data Interface":"SPI","Number of Bits":"8","Package / Case":"20-SSOP (0.209\\\", 5.30mm 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":"20-SSOP","Number of A/D Converters":"1","Voltage - Supply, Analog":"5V","Voltage - Supply, Digital":"5V","Sampling Rate (Per Second)":"50k"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$10.14","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$10.14000","currency":"USD"},{"qty":10,"price":"$9.16400","currency":"USD"},{"qty":25,"price":"$8.73760","currency":"USD"},{"qty":100,"price":"$7.58670","currency":"USD"},{"qty":250,"price":"$7.24576","currency":"USD"},{"qty":500,"price":"$6.60640","currency":"USD"},{"qty":1000,"price":"$5.75397","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/8b71ab447419cac1ea8c40854042a38e.pdf","sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/MAX1112EAP","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/MAX1112EAP when reusing this data.
