Overview
The MAX1169BEUD+T 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, featuring an on-chip 4MHz clock, a +4.096V internal reference, and an I²C-compatible 2-wire serial interface. The MAX1169 operates from a single supply and consumes 5mW at the maximum conversion rate of 58.6ksps. It also includes AutoShutdown™, which powers down the device between conversions, reducing supply current to less than 50µA at a 1ksps throughput rate.
