Data Acquisition - Analog to Digital Converters (ADC) — MAX11902ETP+T

In the field of data acquisition, the main goal of Analog to Digital Converters (ADC) is to provide a fast, accurate and reliable way to convert signals from the analog domain to the digital domain. Among the many ADC components available in the market, the MAX11902ETP+T is an ultra-low power, high-speed ADC that provides a great solution for applications that require efficient and accurate data acquisition, such as medical imaging and telemetry systems.

The MAX11902ETP+T is a 14-bit successive approximation register (SAR) ADC. It is characterized by very low current consumption of only 0.6 mA and a fast acquisition time of 6 μs. The device also features an internal sample-and-hold (SH) circuit and a wide range of a reference voltages, making it an ideal choice for systems with low power requirements and fast data acquisition. This makes the MAX11902ETP+T suitable for applications where the system needs to pull data from several channels without draining the power supply.

The device also features a dynamic power-saving mode which reduces the power consumption down to 0.2 mA for each conversion. This mode can be used in systems that require high accuracy, but with input signals that changes very slowly.

The MAX11902ETP+T has a wide range of input voltage, from -0.3 V to 2.2 V, which further increases its versatility.

The MAX11902ETP+T has an integrated auto-zeroing feature. The device continuously reduces the offset errors of the SAR ADC to a minimum value, thereby improving the device’s accuracy.

The device integrates a temperature sensor, allowing the user to monitor the temperature of the system. This helps to eliminate the need for a dedicated temperature sensor, saving the cost and space in the system board.

The MAX11902ETP+T features an adjustable gain amplifier, allowing the user to adjust the gain of the device for applications that require wider real-world dynamic range.

The device also converts the input voltage into a digital output with a resolution of 14 bits. This allows the user to extract more data from the input signals, enabling the system to capture more information from the analog domain.

The device also features low noise levels, meaning that the ADC is able to capture the small signals accurately. The device also features good linearity, meaning that the conversion of the analog signals to the digital domain happens with minimal errors. The high SNR (Signal to Noise Ratio) of the device ensures that the user can trust the output of the device for accuracy.

The power-saving modes, auto-zeroing feature, and temperature sensing allow the user to improve the efficiency and accuracy of the system without increasing the power requirements of the system. This makes the MAX11902ETP+T ideal for applications where low power consumption and fast data acquisition are the priority.
