NAFE13188B40BSMP

Analog Front End (AFE) Overview

The NAFE13188B40BSMP is a highly configurable industrial-grade analog front-end (AFE) featuring eight universal inputs and a 24-bit sigma-delta ADC. It integrates low-leakage high-voltage 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. Packaged in a 64-pin HVQFN, it operates within a temperature range of -40 °C to +125 °C.

Analog Front End (AFE) Feature Summary

• Eight configurable high-voltage inputs supporting single-ended or differential modes with ranges up to ±25 V
• 24-bit ADC resolution with data rates ranging from 7.5 SPS to 288 kSPS
• Integrated precise voltage and current excitation sources for sensor interfacing
• Low power consumption of 150 mW with robust ESD and surge protection

Analog Front End (AFE) Applications

• Programmable Logic Controller (PLC) I/O modules
• Industrial data acquisition systems
• Process control instrumentation

Analog Front End (AFE) Procurement Notes

Verify the specific ordering suffix B40BSMP corresponds to the reel packing method and standard mark requirements. Confirm that the non-factory-calibrated variant meets system accuracy needs without additional calibration steps. Ensure the 64-pin HVQFN package dimensions align with the PCB footprint specifications.

Analog Front End (AFE) Selection Notes

Select this part when eight channels are required with 24-bit resolution but factory calibration is not mandatory. Compare against the NAFE13388 if factory calibration is needed, or the NAFE13148 if 16-bit resolution suffices. Verify that the low-power mode meets the thermal constraints of the application.

Analog Front End (AFE) Part Context

This component belongs to the NAFEx1388 family, which includes variants with different channel counts, resolutions, and calibration options. It shares pin compatibility and software interfaces with other members like the NAFE13388 and NAFE13148, facilitating scalable design across similar industrial measurement platforms.

Analog Front End (AFE) Replacement Considerations

Direct substitutes within the same family include the NAFE13388B40BSMP, which offers identical hardware features but includes factory calibration coefficients. Other compatible parts in the series include the NAFE13148B40BSMP for 16-bit applications.
