Overview
The MAX1166ACUP+T is a 16-bit, low-power, successive-approximation analog-to-digital converter (ADC) produced by Analog Devices Inc./Maxim Integrated. This device is part of the MAX1165/MAX1166 family, known for its high performance and low power consumption. The MAX1166 is specifically designed with a byte-wide parallel interface, making it suitable for a variety of data-acquisition applications. It operates from a single +4.75V to +5.25V analog supply and a +2.7V to +5.25V digital supply, and it can use either an internal 4.096V reference or an external reference.
The device is available in a 20-pin TSSOP package and is offered in both commercial (0°C to +70°C) and extended temperature ranges (-40°C to +85°C). Its low power consumption and high dynamic performance make it ideal for battery-powered and space-constrained applications.
