That means a negative rail generator or an existing -12 V/-15 V bus on the board — single-supply designs are out. Single-ended input with an internal reference and a 1:1 S/H-to-ADC ratio keeps the external component count low: just the input signal and the supply decoupling. The parallel data interface routes 12 data lines plus control signals to the host, so the PCB trace count is higher than a serial-interface ADC. ## Package, reflow, and the RoHS reality Housed in a 28-SOIC wide-body (7.50 mm width) — a standard surface-mount footprint that places cleanly with any pick-and-place machine. No exotic stencil or reflow profile needed; the wide-body is less prone to tombstoning than the narrow SOIC variant. RoHS non-compliant — this is a leaded (SnPb) part. It cannot ship to RoHS-restricted regions without an exemption. For legacy BOMs that specify tin-lead solder, the MX674AKCWI is the correct bill-of-materials match. The reflow profile follows standard SnPb curves, not the higher lead-free peak. ## Active lifecycle, commercial temperature grade No stock-holding claim — each order is confirmed against the BOM quantity.","metaTitle":"Analog Devices MX674AKCWI 12-bit SAR ADC, 66 kSPS, 28-SOIC","metaDescription":"Analog Devices MX674AKCWI 12-bit SAR ADC, 66 kSPS sampling, single-ended input, parallel interface, 28-SOIC.
