MAX3187CAX+

Overview

The MAX3187CAX+ is a high-precision analog-to-digital converter manufactured by Analog Devices Inc./Maxim Integrated. It features a single-channel, 12-bit resolution with a flash architecture and parallel interface. The device operates on a single 5V supply voltage within an industrial temperature range of -40°C to +85°C. Key performance metrics include a maximum sampling rate of 1Msps, a differential nonlinearity (DNL) of +/- 0.5LSB, and an integral nonlinearity (INL) of +/- 0.5LSB. It utilizes an internal reference and dissipates approximately 60mW of power. The component is housed in a 28-pin SSOP package.

Feature Summary

• Integrated 12-bit flash ADC architecture for rapid conversion
• Internal voltage reference eliminates external components
• Parallel digital output interface for direct microcontroller connection
• Industrial-grade temperature rating for harsh environments

Applications

• Industrial process control systems
• Data acquisition modules
• Medical instrumentation
• Test and measurement equipment

Procurement Notes

Verify the specific suffix 'CAX+' against official manufacturer documentation to confirm pinout compatibility and RoHS status. Ensure the source document explicitly lists this part number as active or available. Cross-reference the datasheet revision date to validate technical specifications before procurement.

Selection Notes

Select this component when a single-channel, 12-bit resolution is required at speeds up to 1Msps. The parallel interface necessitates sufficient GPIO availability on the host processor. Consider the SSOP-28 package size constraints during PCB layout. Verify that the 5V logic levels match the system requirements.

Part Context

This part belongs to the MAX3187 family of high-speed, low-power ADCs from Maxim Integrated. It serves as a specialized data converter solution designed for applications requiring moderate speed and high accuracy without complex serial communication overhead.

Replacement Considerations

Consult official cross-reference guides for verified substitutes. Potential alternatives may include other 12-bit flash ADCs from the same manufacturer series, provided pinouts and electrical characteristics are compatible.
