NAFE11348B40BSE

Analog Front End (AFE) Overview

The NAFE11348B40BSE is an industrial-grade, highly configurable analog front-end (AFE) featuring eight universal high-voltage inputs. It integrates low-leakage multiplexers, a programmable gain amplifier with gains of 0.2 to 0.8 V/V, and a 16-bit Delta-Sigma ADC. The device supports data rates from 7.5 SPS to 288 kSPS with simultaneous 50 Hz/60 Hz line rejection. It provides ±25 V input ranges, ±36 V overvoltage protection, and robust diagnostic capabilities including CRC error detection and temperature monitoring. Designed for precision measurement in harsh environments, it operates between -40 °C and +125 °C.

Analog Front End (AFE) Feature Summary

• Eight configurable HV inputs supporting single-ended or differential signals up to ±25 V
• 16-bit resolution with data rates ranging from 7.5 SPS to 288 kSPS
• Integrated precise voltage sources (REFH/REFL) for end-to-end system self-calibration
• Robust protection including ±36 V overvoltage tolerance and 7.5 kV HBM ESD immunity

Analog Front End (AFE) Applications

• Programmable Logic Controllers (PLCs)
• Industrial I/O modules
• Data acquisition systems
• High-precision sensor interfaces

Analog Front End (AFE) Procurement Notes

Verify the specific ordering suffix B40BSE against the manufacturer's current documentation to confirm tray packaging specifications and dry pack requirements. Ensure the selected variant matches the required 16-bit resolution configuration distinct from the 24-bit NAFE11388 family members.

Analog Front End (AFE) Selection Notes

Select this component when a 16-bit resolution is sufficient for the application's accuracy requirements while maintaining the high-speed performance of the NAFE family. Compare against the NAFE11388 if higher 24-bit resolution is necessary, noting that both share pin compatibility and software architecture.

Analog Front End (AFE) Part Context

This part belongs to the NXP NAFE family of universal analog front-ends. It shares the same 64-pin HVQFN package and functional block diagram as the NAFE11388, differing primarily in ADC resolution (16-bit vs 24-bit). The family is designed for scalable industrial applications with software-defined factory configurations.

Analog Front End (AFE) Replacement Considerations

The NAFE11388B40BS is a functionally compatible alternative within the same package offering 24-bit resolution. Verify software register compatibility and calibration coefficient storage requirements when substituting between the 16-bit and 24-bit variants.
