Analog to Digital Converters (ADCs) convert an analog signal, such as a voltage or current, into a digital signal that can be understood and manipulated by a computer or other digital device. The MAX152CAP is an integrated ADC designed for low cost analog data acquisitions applications. This device has a sample and hold section, a successive approximation register (SAR) analog-to-digital converter (ADC) with an integrated voltage reference and a programmable digital filter.

Features

The MAX152CAP features a voltage reference with line regulation of 0.006% and a temperature coefficient of 16ppm/°C. It also has an input dynamic range of 0V to VREF and an output dynamic range of 0V to 5V. The device also features a programmable digital filter that can filter out noise and unwanted signals. This filter can be programmed to provide a fixed filter frequency or a variable filter frequency based on the input signal.

The MAX152CAP offers a number of other features such as:

• Low cost
• Integrated SAR ADC with low noise and high resolution
• Programmable digital filter for noise reduction
• Integrated voltage reference for increased accuracy and stability
• Proven tested, reliable, and stable performance

Applications

The MAX152CAP is ideal for low cost data acquisitions applications, such as:

• Data loggers
• Monitoring instruments
• Industrial control systems
• Medical data acquisition devices
• Measuring and laboratory instruments

Working Principle

The working principle of the MAX152CAP is relatively simple. It first takes the analog input and samples it using a track and hold section to capture the input signal. Next, the successive approximation register (SAR) performs an analog-to-digital conversion, and converts the analog signal into a digital value. Finally, the digital filter reduces noise and unwanted signals from the output signal. After the noise reduction, the ADC will return the digital signal to the attached device.

The MAX152CAP is a low cost, efficient, and reliable integrated ADC solution for low cost data acquisitions applications.
