MAX14001AAP+T

Analog To Digital Converters (ADC) Overview

The MAX14001AAP+T is a single-channel, isolated analog-to-digital converter (ADC) with programmable voltage comparators and inrush current control. It features 3.75kV RMS integrated isolation between the field-side binary input and the logic-side SPI interface. The device includes an isolated DC-DC converter to power field-side circuitry independently of external signals. Key electrical parameters include a 10-bit SAR ADC resolution, a throughput of 10 ksps, and a 5MHz SPI interface. Logic supply voltage ranges from 1.71V to 5.5V, while the isolated DC-DC input operates at 3.0V to 3.6V. The component is housed in a 20-pin SSOP package.

Analog To Digital Converters (ADC) Feature Summary

• Integrates an isolated DC-DC converter to enable field-side diagnostics without external field power.
• Provides programmable input bias current to attenuate capacitively coupled noise on high-voltage inputs.
• Features a configurable inrush current generator to clean relay contacts via an external high-voltage FET.
• Includes a digital comparator with programmable thresholds and selectable filtering for rapid response.

Analog To Digital Converters (ADC) Applications

• High-voltage binary input modules (12V–300V)
• Distribution automation systems
• Substation automation equipment
• Industrial control multi-range digital input modules

Analog To Digital Converters (ADC) Procurement Notes

Verify that the ordering suffix 'T' corresponds to the tape-and-reel packaging variant rather than the tube-packaged version. Confirm the specific revision level matches the design requirements. Ensure the supplier provides valid UL certification documentation under file E351759 for safety compliance. Cross-reference the manufacturer part number with official Analog Devices or Maxim Integrated catalogs to validate authenticity.

Analog To Digital Converters (ADC) Selection Notes

Select this component when designing systems requiring galvanic isolation for high-voltage binary inputs. The MAX14001 offers fully programmable inrush current magnitude and duration, whereas the MAX14002 has fixed values. Consider the 10-bit resolution and 10ksps sampling rate against system latency requirements. Evaluate the need for internal versus external voltage references based on required accuracy specifications.

Analog To Digital Converters (ADC) Part Context

This component belongs to the MAX14001/MAX14002 family of configurable, isolated 10-bit ADCs designed for multi-range binary inputs. It is manufactured by Analog Devices Inc./Maxim Integrated. The device simplifies field-side circuitry by integrating isolation barriers and power conversion, reducing the bill of materials compared to discrete solutions.

Analog To Digital Converters (ADC) Replacement Considerations

The MAX14002 serves as a functional alternative within the same family but features fixed inrush current settings instead of programmable ones. Verify pin compatibility and register configurations before substitution. Ensure the replacement supports the required isolation voltage and operating temperature range.
