MAX14002AAP+T

Analog To Digital Converters (ADC) Overview

The MAX14002AAP+T is an isolated, single-channel 10-bit analog-to-digital converter (ADC) with programmable voltage comparators and inrush current control. It provides 3.75kV RMS of integrated isolation between the field-side binary input and the logic-side SPI interface. The device features a 10-bit SAR ADC architecture with a throughput of 10ksps and operates within a -40°C to +125°C temperature range. An internal isolated DC-DC converter powers all field-side circuitry, enabling diagnostics even without external field power. The component is housed in a 20-pin SSOP package.

Analog To Digital Converters (ADC) Feature Summary

• Integrates a 10-bit ADC with a 3.75kV RMS isolation barrier for high-voltage binary inputs
• Includes a programmable comparator and fixed inrush current control for relay contact cleaning
• Features an internal isolated DC-DC converter to power field-side circuitry independently
• Supports daisy-chainable SPI communication with configurable filtering options

Analog To Digital Converters (ADC) Applications

• High-Voltage Binary Input (12V–300V)
• Distribution Automation
• Substation Automation
• Industrial Control Multi-Range Digital Input Modules with Individually Isolated Inputs

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing from distributors. Confirm that the MAX14002 variant has fixed inrush parameters rather than the programmable settings found in the MAX14001. Ensure the ordering part number matches the exact Analog Devices/Maxim Integrated designation to avoid confusion with evaluation kits or non-isolated alternatives.

Analog To Digital Converters (ADC) Selection Notes

Select the MAX14002 over the MAX14001 if fixed inrush current magnitude and duration are acceptable, as this simplifies configuration. Verify that the required isolation voltage meets the 3.75kV RMS rating for basic insulation. Ensure the system design accommodates the 20-SSOP package dimensions and the thermal resistance characteristics specified for the operating environment.

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. While the MAX14001 offers fully programmable inrush current parameters, the MAX14002 variant fixes these values to reduce complexity. Both devices share the same core ADC architecture, isolation barrier, and SPI interface capabilities.
