MAX178BEWG

Analog To Digital Converters (ADC) Overview

The MAX178BEWG+ is a precision, calibrated 12-bit analog-to-digital converter (ADC) manufactured by Analog Devices Inc./Maxim Integrated. It utilizes a Successive Approximation Register (SAR) architecture to achieve a sampling rate of 17 kS/s. The device integrates a track-and-hold circuit and an internal reference, supporting single-ended inputs with a parallel interface. It operates within a supply voltage range of 4.75 V to 5.25 V for digital logic and ±5 V to ±7.875 V for analog circuits. Designed for industrial environments, it functions between -40°C and +85°C in a 24-pin SOIC package.

Analog To Digital Converters (ADC) Procurement Notes

Verify the complete ordering suffix, as variants such as MAX178ACWG+ or MAX178AENG+ exist with different temperature grades or packaging. Confirm availability status, as specific sub-models may be discontinued or subject to limited supply constraints. Ensure compatibility with existing parallel bus designs before procurement.

Analog To Digital Converters (ADC) Selection Notes

Select this component for applications requiring a standalone, high-precision 12-bit conversion solution without external calibration needs. The integrated reference simplifies board layout compared to discrete solutions. Verify that the system can accommodate the parallel interface timing requirements and the specified dual-supply voltage ranges for optimal performance.

Analog To Digital Converters (ADC) Part Context

This part belongs to the MAX178 family of precision ADCs from Maxim Integrated. While other members like the MAX17823 focus on battery management or multi-channel acquisition, the MAX178 series specifically targets general-purpose, high-accuracy single-channel data conversion tasks requiring factory-calibrated linearity.
