NAFE13388B40BSE

Analog Front End (AFE) Overview

The NAFE13388B40BSE is a highly configurable industrial-grade analog front-end (AFE) featuring eight high-voltage inputs and a 24-bit sigma-delta ADC. It integrates low-leakage multiplexers, programmable gain amplifiers with gains from x0.2 to x16, and precise voltage/current excitation sources. The device supports data rates up to 288 kSPS with simultaneous 50/60 Hz line rejection. Key specifications include ±25 V input ranges, ±36 V overvoltage protection, and 0.005%FS accuracy after user calibration. It operates within a temperature range of -40 °C to +125 °C and utilizes a 64-pin HVQFN package.

Analog Front End (AFE) Procurement Notes

Verify the ordering part number NAFE13388B40BSE corresponds to the specific tray packaging configuration. Confirm that the factory-calibrated variant matches the application requirements for precision measurements. Ensure compatibility with the 64-pin HVQFN footprint during PCB design validation.

Analog Front End (AFE) Selection Notes

Select this component for applications requiring high channel count and universal input flexibility. The 24-bit resolution and low power consumption make it suitable for battery-operated or thermally constrained environments. Verify that the integrated excitation sources meet the drive requirements for RTDs or load cells without external circuitry.

Analog Front End (AFE) Part Context

This part belongs to the NAFE13388 family, which includes variants with different channel counts, resolutions, and speed profiles. The B40BS suffix indicates the specific package type and marking version. It serves as a superset representative for the family's functional capabilities in industrial signal conditioning.

Analog Front End (AFE) Replacement Considerations

Pin-to-pin compatible alternatives within the NAFE family include NAFE13188B40BS and NAFE73388B40BS. Selection depends on required ADC resolution (16-bit vs 24-bit) and operating speed (low-power vs high-speed). Software compatibility is maintained across the family.
