NAFE71388B40BSE

Analog Front End (AFE) Overview

The NAFE71388B40BSE is a high-speed, industrial-grade analog front-end (AFE) featuring eight configurable universal inputs. It integrates low-leakage high-voltage multiplexers, a programmable gain amplifier (PGA), and a 24-bit Delta-Sigma ADC. The device supports data rates up to 576 kSPS with simultaneous 50 Hz/60 Hz line rejection. Key specifications include ±25 V input ranges, ±36 V overvoltage protection, and robust diagnostic capabilities for predictive maintenance. It operates within a temperature range of -40 °C to +125 °C in a 64-pin HVQFN package.

Analog Front End (AFE) Feature Summary

• High-speed performance: Data rates from 15 SPS to 576 kSPS with 24-bit resolution.
• Universal inputs: Eight channels supporting single-ended or differential configurations up to ±25 V.
• Integrated diagnostics: Includes precise calibration voltage sources, internal temperature sensor, and CRC error detection.
• Robust protection: Features 7.5 kV HBM ESD protection and IEC61000-4-5 2 kV surge immunity.

Analog Front End (AFE) Applications

• Programmable Logic Controller (PLC) I/O modules
• Industrial automation and process control systems
• Data acquisition systems requiring high precision

Analog Front End (AFE) Procurement Notes

Verify the ordering suffix 'B40BSE' corresponds to the specific tray packing method and standard marking configuration as defined in the manufacturer's ordering table. Confirm that the component meets the required thermal-enhanced plastic package specifications for the target application environment.

Analog Front End (AFE) Selection Notes

Select this model when high-speed sampling up to 576 kSPS is required alongside 24-bit resolution. Ensure the system design accommodates the ±7 V to ±24 V high-voltage supply rails and 3.3 V logic levels. Consider the NAFE11388 if lower power consumption is prioritized over maximum speed.

Analog Front End (AFE) Part Context

This component belongs to the NAFEx1388 family of universal analog front-ends. It shares pin compatibility and software interfaces with other family members like the NAFE11388 and NAFE11348, allowing for scalable designs across different performance tiers within industrial measurement applications.

Analog Front End (AFE) Replacement Considerations

NAFE11388B40BSE offers identical packaging but operates at lower speeds (up to 288 kSPS). NAFE11348B40BSE provides 16-bit resolution instead of 24-bit. Verify functional requirements against these variants before substitution.
