It packs a multiplexer, sample-and-hold, and the ADC core in a single 16-QSOP package — a compact fit for multichannel data-acquisition boards where board space is tight. The part accepts either differential or single-ended inputs, configurable per channel, so one device can handle a mix of sensor bridges and single-ended voltage signals without an external mux. ## Supply and signal range — what fits Both analog and digital supplies run from a single 2.7V to 3.6V rail, which maps cleanly onto a 3.3V system bus. No separate analog supply needed, though a clean 3.3V rail with a ferrite bead and a 1 µF decoupling cap at each supply pin keeps the SAR core quiet. The reference can be internal or external — the internal reference saves a component on the BOM if absolute accuracy isn't critical; for ratiometric measurements or tighter drift, an external reference gives you control. ## Package and mounting Housed in a 16-QSOP (0.154\" body width, 3.90 mm), this is a fine-pitch SSOP derivative. The lead pitch is 0.635 mm, which is hand-solderable with a fine tip and flux, but the hot-air station is faster for removal. The package is small enough that thermal mass is low — it lifts clean with a 340°C hot-air nozzle and a gentle twist. ## Temperature grade — where it belongs Rated for 0°C to 70°C commercial temperature range. That puts it in office equipment, benchtop instrumentation, and indoor data loggers — not under the hood or on a factory floor where the ambient hits 85°C. If your design lives in a conditioned space, this is the right cost tier; if it sees an engine bay or a rooftop enclosure, you need the industrial-range sibling. ## Sourcing and lifecycle It is available through independent distribution and quoted to order against an RFQ.","metaTitle":"MAX1246BCEE+ 12-bit SAR ADC, 133 ksps, SPI, 16-QSOP","metaDescription":"MAX1246BCEE+ 12-bit SAR ADC from Analog Devices. 133 ksps sampling rate, SPI interface, differential/single-ended inputs, 2.7V–3.6V supply.
