The SAR architecture delivers a single-cycle conversion with no pipeline delay — every sample is a fresh measurement at the moment the convert command is issued, important for multiplexed sensor scanning where channel-to-channel latency must be deterministic. The input mux accepts either differential or single-ended signals (configurable via the I²C register map), and the ratio of sample-and-hold to ADC is 1:1, meaning each conversion starts from a held snapshot of the selected input. This matters when the input signal changes faster than the conversion time — the hold capacitor freezes the voltage at the start of the SAR cycle. ## Lifecycle, compliance, and sourcing Sourced through independent distribution channels; availability and current pricing confirmed at RFQ against your target quantity.","metaTitle":"MAX1239MEEE-T ADC, 12-bit, 94.4kSPS, I²C, 16-QSOP","metaDescription":"MAX1239MEEE-T 12-bit SAR ADC from Analog Devices, 94.4kSPS, I²C interface, differential/single-ended inputs, -40 to 85°C.

The 12-bit resolution gives 4096 codes across the input range; at 94.4 kSPS each conversion completes in roughly 10.6 µs, fast enough for multi-channel sensor scanning where each channel needs a fresh reading every millisecond or so."},{"question":"Does the MAX1239MEEE-T accept differential or single-ended inputs?","answer":"Both. The input multiplexer can be configured for differential pairs or single-ended signals via the I²C register map. The SAR core uses a single sample-and-hold per conversion, so the selected input is captured at the start of the conversion cycle with no pipeline delay."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/MAX1239MEEE-T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/MAX1239MEEE-T when reusing this data.
