10-bit SAR ADC at 94.4k samples/s — I²C interface
The MAX11611EEE+T is a 10-bit successive-approximation-register (SAR) ADC from Analog Devices, sampling at 94.4k samples per second over an I²C data interface. That sample rate is enough to digitise audio-band sensor signals or multiple slow analog channels with a single converter. Inputs can be configured as differential or single-ended, with the mux feeding a sample-and-hold in a 1:1 ratio. The part handles 6 or 12 input channels depending on the configuration. Reference selection is flexible: use the internal reference for a self-contained design, or feed an external reference when tighter accuracy or ratiometric measurement is needed.
The 16-QSOP package is a 3.90 mm-wide SSOP footprint — a common 0.154-inch body width that routes easily on a two-layer board. Surface-mount assembly with no exposed pad means no thermal-via planning.
