The SAR architecture gives you a deterministic conversion time with no pipeline delay, so the sample timing is predictable in a control loop. ## Input mux flexibility — 8, 15, or 16 channels The input multiplexer can be configured as 8 differential, 15 pseudo-differential, or 16 single-ended channels — the same silicon handles all three topologies, so one BOM line serves multiple board variants by changing the firmware configuration. The MUX-S/H-ADC signal chain (1:1 S/H-to-ADC ratio) means each channel gets a dedicated sample-and-hold before conversion, avoiding crosstalk between adjacent inputs during the acquisition window. Reference type is external — you supply the VREF pin with the voltage that sets the full-scale range. This lets you scale the input span to match the sensor output (e.g., 2.5 V for a ratiometric bridge, 3.3 V for a 0-10 V divider) without losing LSB resolution. The external reference also means the ADC's gain accuracy tracks the reference drift, not an internal bandgap. The SPI data interface requires four wires — SCLK, DIN, DOUT, and CS — plus the VREF and supply pins. No parallel bus or external timing controller needed, so the routing stays tight around the ADC on a 2-layer board if the ground plane is continuous under the package. Sourced to order against your BOM quantity through independent distribution.","metaTitle":"MAX11128ATI+ 12-bit SAR ADC, 1 Msps, 28-TQFN","metaDescription":"MAX11128ATI+ 12-bit SAR ADC from Analog Devices, 1 Msps sampling, 8/15/16-channel MUX, SPI interface, -40 to +125°C, 28-TQFN.
