Overview
The MAX1188ACUP+ 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 MAX1178/MAX1188 family, known for its high performance and low power consumption. It operates from a single +4.75V to +5.25V analog supply and features a separate digital supply input for direct interface with +2.7V to +5.25V digital logic. The MAX1188 is particularly suited for applications requiring a bipolar analog input voltage range of ±10V, making it ideal for industrial process control, instrumentation, and medical applications.
