MAX125CCAX+D

ADCs/DACs - Special Purpose Overview

The MAX125CCAX+D is a high-speed, multichannel, 14-bit data-acquisition system (DAS) featuring four simultaneous-sampling track/holds. It contains a successive-approximation ADC with a 3µs conversion time per channel and an internal +2.5V reference. The device supports ±5V input ranges and fault-protected inputs tolerant to ±17V. Operating on ±5V supplies, it utilizes a programmable onboard sequencer and a high-speed parallel DSP interface for efficient data access without wait states.

ADCs/DACs - Special Purpose Feature Summary

• Four simultaneous-sampling T/H amplifiers with two multiplexed inputs each, totaling eight single-ended inputs
• Internal +2.5V reference or external reference operation with buffered output
• Programmable onboard sequencer supporting one to four channels per CONVST pulse
• Fault-protected input multiplexer tolerant to ±17V overvoltage conditions

ADCs/DACs - Special Purpose Applications

• Multiphase Motor Control
• Power-Grid Synchronization
• Power-Factor Monitoring
• Digital Signal Processing
• Vibration and Waveform Analysis

ADCs/DACs - Special Purpose Procurement Notes

Verify the commercial temperature range (0°C to +70°C) associated with the CC suffix against system requirements. Confirm RoHS compliance status for the specific manufacturing lot. Ensure the SSOP-36 package dimensions match the PCB footprint design. Validate supply voltage stability within ±5% limits during operation.

ADCs/DACs - Special Purpose Selection Notes

Select this component when simultaneous sampling of multiple phases is required to preserve relative timing information. Choose the MAX125 variant for ±5V input ranges; use MAX126 for ±2.5V ranges. Ensure the host processor supports the bidirectional parallel interface timing specifications. Verify that the 16MHz external clock requirement fits the system clock architecture.

ADCs/DACs - Special Purpose Part Context

This part belongs to the MAX125/MAX126 family of 14-bit DAS devices. The CC suffix denotes the commercial temperature range (0°C to +70°C), while CE indicates extended range (-40°C to +85°C). The +D suffix typically signifies lead-free and RoHS-compliant packaging variants within the Maxim Integrated product line.

ADCs/DACs - Special Purpose Replacement Considerations

Direct pin-compatible replacements include MAX125CEAX+D for extended temperature operation. MAX126CCAX+D offers identical functionality with a reduced ±2.5V input range. Cross-model substitution requires verifying input voltage compatibility and thermal performance constraints.
