MAX1802EHJ+

Overview

The MAX1802EHJ+ is a high-speed, 12-bit analog-to-digital converter manufactured by Analog Devices Inc./Maxim Integrated. It features a sampling rate of 40Msps and supports both single-ended and differential input configurations. The device operates on a single 3V supply voltage and utilizes a serial interface for data communication. Packaged in a 28-pin TQFP format, it is designed for applications requiring precise signal acquisition with low power consumption.

Feature Summary

• Integrates a 12-bit successive approximation register (SAR) ADC architecture for efficient data conversion.
• Supports flexible input modes including single-ended and fully differential configurations.
• Features a simple serial interface compatible with standard microprocessor protocols.
• Operates from a single 3V power supply to facilitate low-voltage system designs.

Applications

• Portable medical instrumentation
• Industrial process control systems
• Battery-powered measurement devices

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix matches project requirements. Check current availability status as lifecycle changes may occur. Ensure compliance with RoHS directives if required by regional regulations. Validate package integrity upon receipt.

Selection Notes

Evaluate the 40Msps sampling rate against application bandwidth needs. Consider the 12-bit resolution for required accuracy levels. Assess power consumption constraints relative to the single 3V supply operation. Compare physical dimensions of the 28-TQFP package with board layout limitations. Review serial interface timing requirements for system integration.

Part Context

This component belongs to the MAX1802 family of high-speed ADCs. It shares architectural similarities with other Maxim integrated SAR converters but offers specific performance characteristics tailored for medium-speed applications. The series emphasizes ease of use and low power operation within the analog-to-digital conversion market segment.
