It accepts both differential and single-ended inputs through an internal multiplexer (configurable as 4 differential or 8 single-ended channels), so a single part can handle a mix of bridge sensors and single-ended voltage outputs without external signal conditioning. ## Supply and interface — one rail, SPI bus The SPI data interface (up to the ADC's conversion rate) connects directly to most microcontrollers' SPI peripherals; the external or internal reference option lets you trade off accuracy against BOM cost. ## Package and temperature grade — board-fit and environment Housed in a 20-TSSOP (4.40 mm width) surface-mount package, supplied in tube — not tape-and-reel, so factor that into your pick-and-place feeder setup if you're running high-volume assembly. ROHS3 compliant (lead-free, no restricted substances beyond the standard exemptions), which clears EU and global regulatory gates without a waiver.","metaTitle":"MAX1149BEUP+ 14-Bit SAR ADC, 116k SPS, 20-TSSOP","metaDescription":"MAX1149BEUP+ 14-bit SAR ADC from Analog Devices, 116k sampling rate, differential/single-ended inputs, SPI interface, -40°C to 85°C, 20-TSSOP.
