Overview
The MAX1081BCUP, produced by Analog Devices Inc./Maxim Integrated, is a high-performance, low-power, 10-bit analog-to-digital converter (ADC). This device combines an 8-channel analog-input multiplexer, a high-bandwidth track/hold (T/H) circuit, and a serial interface, making it suitable for a variety of applications requiring multiple analog inputs and high conversion speeds.
The MAX1081 operates from a single supply voltage of +2.7V to +3.6V, which is particularly beneficial for power-sensitive designs. It features an internal +2.5V reference and a reference-buffer amplifier, allowing for both internal and external reference voltage configurations.
