It integrates an input multiplexer accepting either 4 differential or 8 single-ended analog inputs, plus an on-chip temperature sensor for die-temperature monitoring. The SPI-compatible serial interface and single 2.7V to 3.6V supply rail (shared by analog and digital domains) simplify board layout and power budgeting. Housed in a 16-pin QSOP package, this ADC targets industrial sensor acquisition, data-logging, and portable instrumentation operating in the 0°C to 70°C commercial temperature range. ## 300k SPS — what it buys you At 300k samples per second, the MAX1227BCEE+ can digitize input signals up to roughly 150 kHz bandwidth (Nyquist-limited), making it suitable for multi-channel data acquisition where each channel is scanned sequentially. The 1:1 S/H-to-ADC ratio means the sample-and-hold captures one sample per conversion cycle; the internal SAR architecture delivers a conversion result on every clock cycle with no pipeline delay, so the throughput is deterministic and easy to time in firmware. ## Input configuration and reference options The internal mux lets you configure the ADC for 4 differential inputs (each using two pins) or 8 single-ended inputs referenced to common ground. The reference type is selectable between an internal bandgap reference and an external reference applied to a dedicated pin, giving flexibility between absolute accuracy and ratiometric measurements. Single 3.3 V supply operation keeps the BOM lean — no separate analog rail needed.","metaTitle":"MAX1227BCEE+ 12-Bit SAR ADC, 300k SPS, 16-QSOP","metaDescription":"MAX1227BCEE+ 12-bit SAR ADC from Analog Devices with 300k sampling rate, SPI interface, 4/8 input mux, internal temperature sensor. 2.7V-3.6V supply.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Package":"Tube","Features":"Temperature Sensor","Input Type":"Differential, Single Ended","Architecture":"SAR","Configuration":"MUX-S/H-ADC","Mounting Type":"Surface Mount","Data Interface":"SPI","Number of Bits":"12","Package / Case":"16-SSOP (0.154\\\", 3.90mm Width)","Reference Type":"External, Internal","Ratio - S/H:ADC":"1:1","lifecycle_stage":"eol_hot","Number of Inputs":"4, 8","Operating Temperature":"0°C ~ 70°C","Supplier Device Package":"16-QSOP","Number of A/D Converters":"1","Voltage - Supply, Analog":"2.7V ~ 3.6V","Voltage - Supply, Digital":"2.7V ~ 3.6V","Sampling Rate (Per Second)":"300k"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$17.33","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$17.33000","currency":"USD"},{"qty":10,"price":"$15.92600","currency":"USD"},{"qty":25,"price":"$15.26560","currency":"USD"},{"qty":100,"price":"$13.45030","currency":"USD"},{"qty":250,"price":"$12.79012","currency":"USD"},{"qty":500,"price":"$11.96496","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/7ea35c5bc80b7e0ef367fd8c1d6ed694.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the sampling rate of MAX1227BCEE+?","answer":"The MAX1227BCEE+ samples at 300k samples per second (300 kSPS), which supports input signal bandwidths up to approximately 150 kHz."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/MAX1227BCEE","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/MAX1227BCEE when reusing this data.
