The working principle of the MAX1187AEUI+ is based on the capacitive charge transfer integration (CTI) method, which converst analog signals into digital codes.The device has an input register and an output register and uses two identical sample-and-hold capacitors to keep the input voltage stable during the conversion.The analog signal to be converted is first stored in the input register, then transferred to the output register.This transfer is done by switching the two capacitors at precisely the right moment, with the timing of the switch controlled by the PLL.The output register is then compared against a reference voltage and if the stored voltage is larger than the reference voltage, the corresponding digital code is outputted.

The output code associated with the analog voltage stored in the input register is proportional to the integral of the time-varying voltage.This means that, for a given period of time, the output code is dependent on the total amount of charge transferred to the output register.Therefore, the MAX1187AEUI+ converts the input analog voltage into a digital value that is proportional to the integral of the input voltage. This is referred to as the charge-transfer (CT) integration method.

In addition to the CT integration method, the MAX1187AEUI+ also supports the track-and-hold (T&H) mode of operation.In this mode, the analog voltage is tracked and then held while the conversion is taking place.The result of this method is a more accurate conversion of the analog signal into digital codes, resulting in improved conversion accuracy and lower noise.The MAX1187AEUI+ is therefore an excellent choice when high accuracy and low noise are required.

In summary, the MAX1187AEUI+ is an advanced analog-to-digital converter (ADC) system from Maxim Integrated that is ideal for general-purpose data acquisition applications. It supports both single-ended and differential inputs in an industrial temperature range from -40 to +85°C, and features an integrated low-jitter phase-locked loop (PLL) and an integrated clock generation. The conversion rate of the MAX1187AEUI+ is up to 1.25MSPS and the device supports an industry-standard SPI interface. The MAX1187AEUI+ is suitable for use in a variety of data acquisition applications, including medical imaging and process control. The device is based on the capacitive charge transfer integration (CTI) method and also supports the track-and-hold (T&H) mode of operation for improved accuracy and noise levels.
