12-bit SAR ADC with I²C — what it is and where it fits
The MAX11614EEE+ is a 12-bit successive-approximation-register (SAR) ADC from Analog Devices, sampling at 94.4 ksps over an I²C interface. It integrates an input multiplexer that accepts either 4 differential or 8 single-ended signals, configurable per conversion sequence, plus a track-and-hold front end. The part runs on a single 5V supply for both analog and digital rails, and it is specified over the -40°C to 85°C industrial temperature range. Typical applications include multi-channel sensor acquisition in industrial controllers, data loggers, and battery-monitoring systems where the I²C bus keeps wiring simple and the SAR architecture delivers consistent conversion latency.
Differential or single-ended — pick the input mode that matches your sensor
The internal MUX lets you configure each input pair as differential or single-ended. In differential mode you get the full 12-bit dynamic range with common-mode rejection.
Package and mounting — 16-QSOP footprint
The MAX11614EEE+ comes in a 16-pin QSOP package (3.90 mm body width, 0.154-inch pitch), surface-mount only. The part ships in a tube.
