Overview
The MAX1162BEUB, produced by Analog Devices Inc./Maxim Integrated, is a low-power, 16-bit analog-to-digital converter (ADC) designed for high-performance and low-power applications. This successive-approximation ADC features automatic power-down, fast 1.1µs wakeup, and a high-speed SPI™/QSPI™/MICROWIRE™-compatible interface. It operates with a single +5V analog supply and has a separate digital supply, allowing direct interfacing with +2.7V to +5.25V digital logic. The MAX1162 is ideal for battery-powered and data-acquisition applications due to its excellent dynamic performance, low power consumption, and small package size.
