It accepts either four differential or eight single-ended inputs (configured via the MUX), and communicates over an SPI interface. The 133k samples-per-second throughput is the practical ceiling for capturing audio-band or slow-moving sensor signals — think thermocouple arrays, pressure transducers, or battery-monitoring channels where 12-bit resolution is sufficient and you need to digitize multiple inputs through one converter. ## Supply range and temperature grade — fit for industrial and mixed-voltage boards Both the analog and digital supply pins accept 2.7 V to 5.25 V, so you can run the ADC from a single 3.3 V or 5 V rail without needing a separate analog regulator. The -40°C to 85°C operating range covers industrial enclosures, outdoor telecom cabinets, and under-hood automotive (non-AEC) environments. If your design lives in a conditioned lab or office, the commercial-grade sibling might save a few cents, but this part gives you headroom for temperature excursions without requalifying. ## 20-SSOP package — rework-friendly, but watch the moisture sensitivity If the tube has been open past that window, a 24-hour bake at 60°C before reflow is cheap insurance against popcorning. The tube shipping medium means the parts are already aligned for pick-and-place, though you may want to transfer them to a tray for machine feed. ## Active lifecycle — no LTB pressure, but plan for long-term supply The MAX147AEAP+ carries an Active lifecycle status and is ROHS3 compliant. For production programs that will run beyond a few years, it is worth checking with your distributor periodically for any PCN — Maxim (now part of Analog Devices) has been known to consolidate product lines, and an active status today does not guarantee availability five years out. Sourcing through independent distribution gives you a second path if the authorized channel tightens.","metaTitle":"MAX147AEAP+ 12-bit SAR ADC, 133k SPS, SPI, 20-SSOP","metaDescription":"Maxim Integrated MAX147AEAP+ 12-bit SAR ADC, 133k sampling rate, SPI interface, 2.7V-5.25V supply, -40°C to 85°C, 20-SSOP.
