NAFE11388B40BSE

Analog Front End (AFE) Overview

The NAFE11388B40BSE 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 24-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 0.005% FS accuracy after user calibration. Operating on ±7 V to ±24 V HV and 3.3 V LV supplies, it consumes 125 mW and operates between -40 °C and +125 °C in a 64-pin HVQFN package.

Analog Front End (AFE) Feature Summary

• Eight configurable HV inputs supporting single-ended or differential signals up to ±25 V
• 24-bit resolution with ENOB of 17 bits at 72 kSPS
• Integrated precise voltage sources for end-to-end system self-calibration
• Robust protection including 7.5 kV HBM ESD and IEC61000-4-5 2 kV surge immunity

Analog Front End (AFE) Applications

• Data acquisition systems
• PLC and DCS I/O modules
• Industrial automation and process control

Analog Front End (AFE) Procurement Notes

Verify the ordering suffix B40BS corresponds to the HVQFN64 package and standard marking. Confirm the specific packing method (Tray vs Reel) matches the required manufacturing process. Ensure the temperature range TA = -40 °C to +125 °C meets environmental requirements.

Analog Front End (AFE) Selection Notes

Select this part for applications requiring high precision and multi-channel scanning. Compare against NAFE11348 if 16-bit resolution suffices for lower power consumption. Consider NAFE71388 if higher speed up to 576 kSPS is needed. Verify PGA gain settings align with the expected signal amplitude.

Analog Front End (AFE) Part Context

This component belongs to the NXP NAFE family of universal analog front-ends. It is pin-to-pin and software-compatible with other members like NAFE11348 and NAFE71388, facilitating scalable design across different performance tiers within industrial measurement systems.

Analog Front End (AFE) Replacement Considerations

NAFE11348B40BS offers 16-bit resolution with lower power consumption. NAFE71388B40BS provides high-speed operation up to 576 kSPS. Both are compatible with the same package and interface.
