Introduction

The MAX11161EUB+ is an analog-to-digital converter (ADC) from Maxim Integrated Products. It is designed for a wide range of data acquisition applications, from sample and hold converters to data loggers and more. The MAX11161EUB+ provides a high speed, low power, low cost, single-chip solution to meet these data acquisition needs. In this article, we will discuss the application fields and working principles of the MAX11161EUB+.

Technical Specifications

The MAX11161EUB+ is an ultra-low power, 14-bit ADC operating from a single +3V power supply. It has a sampling rate of 8kSPS and achieves a 12-bit ENOB of 72dB SNDR signal-to-noise ratio at 200kHz input signal frequency. The MAX11161EUB+ features a low noise input, with a differential input range of 0-2V and an unipolar range of 0V to GND. It supports a wide range of single-ended and differential input signal configurations.

Applications

The MAX11161EUB+ is ideal for a wide range of data acquisition applications, from sample and hold converters to data loggers. It supports a wide range of single-ended and differential input signal configurations, making it suitable for many different applications. Additionally, the MAX11161EUB+ has an input power supply range of 2.7-3.6V, making it suitable for systems with a limited power supply.The MAX11161EUB+ is especially suitable for high-accuracy and low-power data acquisition applications. It can be used to measure high-precision analog signals and power efficiency is of critical importance. The device is also ideal for applications that require high data acquisition rate, such as image processing, medical imaging and audio/video/optical signal capture and analysis. The MAX11161EUB+ is ideal for portable and battery-powered products, as it operates from a single +3V power supply and consumes only 60μA at 8kSPS.

Working Principle

The MAX11161EUB+ is a successive approximation register (SAR) ADC. SAR converters work by comparing the input voltage to a series of reference voltages, to determine the digital code that corresponds to the input voltage. The MAX11161EUB+ has a 14-bit SAR converter, which means that it has 16,384 (214) different reference levels.The MAX11161EUB+ also includes a multiplexer that can be used to switch between multiple input channels, depending on the application. This allows the device to measure multiple signals simultaneously. The MAX11161EUB+ also includes an on-chip sample and hold circuit that allows it to capture and hold an input signal, ensuring that the ADC reads the same value each time it is converted.

Conclusion

The MAX11161EUB+ is a low-power, low-cost, single-chip, 14-bit ADC designed for a wide range of data acquisition applications, from sample and hold converters to data loggers. It supports a wide range of single-ended and differential input signal configurations, and can operate from a single +3V power supply. The MAX11161EUB+ is ideal for high-accuracy and low-power data acquisition applications. It has an input power supply range of 2.7-3.6V and consumes only 60μA at 8kSPS. The MAX11161EUB+ uses a successive approximation register (SAR) converter, and includes a multiplexer and an on-chip sample and hold circuit.
