Overview
The MAX1178CCUP+ 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 suitability for battery-powered data-acquisition applications. The MAX1178CCUP+ 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.
It is characterized by its excellent AC performance, including a Total Harmonic Distortion (THD) of -100dB, and high DC accuracy with an Integral Nonlinearity (INL) of ±2 LSB. The device is available in a 20-pin TSSOP package and is fully specified over the -40°C to +85°C extended temperature range and the 0°C to +70°C commercial temperature range.
