MAX197BEWI+

Data Acquisition – ADCs/DACs – Special Purpose

The MAX197BEWI+ is an integrated analog-to-digital converter designed for low-power, medium-speed applications. The device combines 7-bit voltage and current measurement with a 5-bit scale factor register in a single-chip package. It offers range-dependent and cycle-by-cycle averaging of voltage and current, as well as absolute measurement of voltage and current. The device uses voltage and current input signals to calculate RMS and THD energy values that can be used to estimate energy consumed in lighting applications.

The device performs processing and conversions of low-level signals and can be used in a variety of applications in various industries and environments. For example, in the energy management sector, the MAX197BEWI+ enables energy-saving activities and improved energy efficiency. In the automotive industry, it is an ideal solution for diagnostics and system monitoring, as well as for detecting anomalies in monitoring systems.

The MAX197BEWI+ is designed to measure voltage, current, temperature, and humidity with accuracy and repeatability. The device is also suitable for measuring vibration, pressure, and strain. Through its 5-bit resolution, it can detect span shifts and shifts in zero values, thereby enabling better system monitoring and reliability.

The device is capable of measuring analog signals with a frequency range of 50KHz to 1.4MHz ( for DC, 0.3V to +3V, ±3V) and features an on-chip temperature compensator that can improve accuracy. Additionally, a reference voltage is provided to the user while the waveform input is sampled and digitized.

The MAX197BEWI+ supports various operating modes, such as continuous, consecutive sampling, and cyclic sampling. In continuous mode, the device continuously digitalizes input signals and produces a sequence of 7-bit codes. In consecutive sampling mode, the device performs a single conversion and digitalizes the signals from four different analog inputs. In cyclic mode, the device digitalizes all four analog signals at the same time and updates the output as soon as all four analog signals have been digitalized.

The device also features an on-board ADC and DAC, which provides a flexible and powerful platform for developing smart electronics. The DAC supports linear and logarithmic curves, allowing a variety of signal processing applications. The device includes two channels of 12-bit wide bandwidth and 8-channel multiplexed analog-to-digital converters.

The MAX197BEWI+ also has powerful signal processing capabilities, including signal filters, temperature compensation, calculation of temperature-dependent parameters, and signal normalization. It is also equipped with peak detector and zero-cross detector functions, which can provide information and enable advanced control calculations.

The device has an on-chip Real-Time Time Stamp (RTTS) generator that can be used for cyclical data acquisition and storage. It also supports I²C protocol and serial Flash memory, thereby providing a reliable, low-power and cost-effective solution for long-term data storage and analysis.

Overall, the MAX197BEWI+ provides a low-power, compact solution for low-level signal measurement and processing. It is suitable for a wide range of applications, including energy management, automotive, process control, and home automation. The device enables accurate, reliable, and repeatable measurements and can be used in a number of industries and environments.
