Overview
The MAX1168CEEG is a multichannel, 16-bit analog-to-digital converter (ADC) produced by Analog Devices Inc./Maxim Integrated. This device is part of the MAX1167/MAX1168 family, known for its low power consumption, high resolution, and versatile interface options. The MAX1168CEEG features a successive-approximation ADC architecture, an integrated +4.096V reference, and a high-speed SPI/QSPI/MICROWIRE-compatible serial interface. It is designed to operate with a single +5V analog supply and can interface directly with digital logic ranging from +2.7V to +5.5V.
