Overview
The MAX1169CCUD+ is a low-power, 16-bit successive-approximation analog-to-digital converter (ADC) produced by Analog Devices Inc./Maxim Integrated. This device is designed for high-performance and low-power applications, making it suitable for a variety of use cases. The MAX1169 features an on-chip 4MHz clock, a +4.096V internal reference, and an I²C-compatible 2-wire serial interface that supports both fast and high-speed modes. It operates from a single supply and consumes 5mW at the maximum conversion rate of 58.6ksps. The device also includes automatic power-down, reducing supply current to less than 50µA at a 1ksps throughput rate, which is particularly beneficial for battery-powered systems.
