NAFE13148B40BSMP

Analog Front End (AFE) Overview

The NAFE13148B40BSMP is a highly configurable industrial-grade analog front-end (AFE) featuring eight universal high-voltage inputs and a 16-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 and offers ±25 V input ranges with overvoltage protection up to ±36 V. Designed for precision measurement, it includes internal calibration sources, diagnostic circuits, and operates within a temperature range of -40 °C to +125 °C.

Analog Front End (AFE) Feature Summary

• Eight configurable HV inputs supporting single-ended or differential modes with ranges up to ±25 V
• 16-bit ADC resolution with data rates ranging from 7.5 SPS to 288 kSPS
• Integrated precise voltage and current excitation sources for sensor interfacing
• Robust protection including ±36 V overvoltage tolerance and IEC61000-4-5 2 kV surge immunity

Analog Front End (AFE) Applications

• Programmable Logic Controllers (PLCs)
• Industrial Data Acquisition Systems
• Process Control I/O Modules

Analog Front End (AFE) Procurement Notes

Verify the specific ordering suffix B40BSMP corresponds to the 64-pin HVQFN package in a 13-inch reel packing method. Confirm that the 16-bit ADC resolution variant matches the system requirements, as this part differs from the 24-bit NAFE13388 family members. Ensure the non-factory-calibrated nature of this specific model is acceptable for the intended application's accuracy needs.

Analog Front End (AFE) Selection Notes

Select this component when eight channels of universal input are required with 16-bit resolution. It is suitable for applications prioritizing lower power consumption over the highest speed variants. Designers must account for the lack of factory calibration coefficients if high absolute accuracy without user calibration is required. The device requires both high-voltage (±7 V to ±24 V) and low-voltage (3.3 V) power supplies.

Analog Front End (AFE) Part Context

This part belongs to the NAFE13388 product family, which serves as the superset documentation for various configurations. The NAFE13148 specifically denotes the 16-bit ADC resolution and non-factory-calibrated version within the low-power subset of the family. It shares pinout and software compatibility with other family members like the NAFE13388 and NAFE13188.

Analog Front End (AFE) Replacement Considerations

Other parts in the NAFE family, such as NAFE13188 or NAFE13388, offer pin-to-pin compatibility. Selection depends on whether higher resolution (24-bit), factory calibration, or different channel counts are needed.
