Its MUX-S/H-ADC architecture handles either 4 pseudo-differential or 8 single-ended inputs, giving you channel-count flexibility without a separate front-end mux. The parallel data interface pushes the full 10-bit word on each conversion clock, so the host controller reads the result in one bus cycle — no serial shift-out latency. This matters when you are interleaving multiple ADC reads in a tight control loop. ## Supply rails and reference options for system integration The reference can be driven externally or drawn from the internal bandgap — external gives you ratiometric accuracy tied to a precision source; internal saves a reference IC if the system can tolerate the ±1 % initial tolerance. The tube delivery means the parts arrive oriented for pick-and-place, not loose in a reel — plan your feeder setup accordingly.","metaTitle":"MAX1090AEEI+ ADC, 10-Bit SAR, 400k SPS, 28-QSOP","metaDescription":"MAX1090AEEI+ 10-bit SAR ADC, 400k samples per second, 4/8 input MUX, parallel interface, -40 to 85°C.
