MX7581LN

ADCs/DACs - Special Purpose Overview

The MX7581LN is a CMOS single-chip 8-bit, 8-channel Data Acquisition System (DAS) manufactured by Analog Devices Inc. / Maxim Integrated. It integrates an 8-bit A/D converter, an 8-channel multiplexer, an 8x8 dual-port RAM with conflict logic, and microprocessor-compatible I/O logic. Designed for direct interface with most microprocessors when paired with an external voltage reference, it serves as a complete DAS solution. The device operates within a commercial temperature range of 0°C to +70°C and is housed in a 28-pin DIP package.

ADCs/DACs - Special Purpose Feature Summary

• Integrated 8-bit SAR ADC with 8-channel analog multiplexer
• On-chip 8x8 dual-port RAM for automatic data storage and conflict-free access
• Microprocessor-compatible parallel interface supporting Z80, 8085, and 6800 architectures
• Supports ratio measurement capabilities for enhanced accuracy

ADCs/DACs - Special Purpose Applications

• Digital signal processing systems requiring rapid multi-channel data acquisition
• Data loggers for environmental and industrial parameter recording
• Automated test equipment for efficient test data collection
• Process control systems for real-time parameter monitoring

ADCs/DACs - Special Purpose Part Context

The MX7581LN belongs to the MAX161/MX7581 family of CMOS data acquisition systems. It is functionally similar to the MAX161 but lacks the enhanced conversion speed, lower zero error/drift, and military temperature grade options available in the MAX161 variant. Both devices share pin compatibility and core architecture, differing primarily in performance specifications and temperature ranges.
