Overview
The MAX1080BCUP, produced by Analog Devices Inc./Maxim Integrated, is a 10-bit analog-to-digital converter (ADC) that combines an 8-channel analog-input multiplexer, high-bandwidth track/hold (T/H), and a serial interface. This device is designed for high conversion speed and low power consumption, making it suitable for a variety of applications. The MAX1080 operates from a single +4.5V to +5.5V supply, while the MAX1081, a related model, operates from a single +2.7V to +3.6V supply. Both devices feature software-configurable unipolar or bipolar and single-ended or pseudo-differential inputs.
