It accepts either differential or single-ended inputs through a front-end multiplexer that connects 4 or 8 channels to the sampling network. The 133k samples-per-second throughput suits medium-speed data acquisition, process monitoring, and control-loop feedback. ## Sampling rate and input channel count At 133k SPS the conversion time per channel is roughly 7.5 µs, including the multiplexer settling and SAR conversion. With 8 single-ended inputs the aggregate throughput drops to about 16.6k samples per channel per second — still fast enough for most multi-channel sensor arrays. The 4-channel differential mode halves the input count but doubles the common-mode rejection for noisy field wiring. The internal reference eliminates the need for an external voltage source, saving one component and one board trace. For applications that need a ratiometric measurement against a precision external reference, the reference type can be switched to external. ## Temperature grade and supply range The Tape & Reel option is suited for automated pick-and-place assembly. ## Compliance and lifecycle status Analog Devices lists the MAX149BEAP+T as an active product with RoHS3 compliance.","metaTitle":"MAX149BEAP+T ADC, 10-Bit SAR, 133k SPS, 20-SSOP","metaDescription":"MAX149BEAP+T 10-bit SAR ADC from Analog Devices. 133k sampling rate, SPI, 4/8 input channels.
