MAX139CMH+D

ADCs/DACs - Special Purpose Overview

The MAX139CMH+D is a specialized analog-to-digital converter (ADC) and data acquisition system (DAS) integrated circuit manufactured by Analog Devices Inc./Maxim Integrated. It features a 3.5-digit resolution architecture housed in a 44-MQFP (10x10 mm) surface-mount package. The device operates on a single power supply ranging from 2.5V to 7V and supports two input channels. Designed for industrial and commercial environments, it functions within a temperature range of 0°C to +70°C. Key specifications include a power dissipation rating of 800 mW and compliance with RoHS3 standards.

• Dual-channel input support within a compact 44-MQFP package
• Single-supply operation compatible with 2.5V to 7V voltage ranges
• Industrial-grade thermal performance with 800 mW power dissipation

ADCs/DACs - Special Purpose Applications

• Panel meters requiring direct LCD interface
• Data acquisition systems with dual-channel input needs
• Industrial process control instrumentation
• Portable battery-powered measurement devices

ADCs/DACs - Special Purpose Procurement Notes

Verify component authenticity through authorized distributors or the manufacturer directly. Confirm RoHS3 compliance status prior to integration. Check current availability as supply may be restricted. Ensure proper handling for moisture-sensitive device (MSL 3) during storage and assembly processes.

ADCs/DACs - Special Purpose Selection Notes

Select this component when a combined ADC and LCD driver solution is required for 3.5-digit displays. Verify that the 2.5V-7V single-supply range matches the system power architecture. Ensure the 44-MQFP footprint fits the PCB layout constraints. Consider the 0°C to +70°C operating temperature range against environmental conditions.

ADCs/DACs - Special Purpose Part Context

This part belongs to the MAX139 series of specialized ADC/DAC components. It shares the 44-MQFP form factor with related models like the MAX136 and MAX138 but offers distinct channel configurations and internal reference structures. The 'D' suffix typically denotes specific tape-and-reel or tray packaging variations within the Maxim product line.
