NAFE13144B40BSK

Analog Front End (AFE) Overview

The NAFE13144B40BSK is a universal analog front-end (AFE) featuring four high-voltage inputs and a 16-bit sigma-delta ADC. It supports ±25 V input ranges with programmable gain from x0.2 to x16, enabling measurement of voltage, current, RTD, and thermocouple signals. The device integrates precise excitation sources, low-drift references, and diagnostic supervisory circuits. Operating at data rates up to 288 kSPS, it provides simultaneous 50/60 Hz line rejection and robust EMC protection. Designed for industrial environments, it operates within a -40 °C to +125 °C temperature range.

Analog Front End (AFE) Feature Summary

• Four configurable HV inputs supporting single-ended or differential modes 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 driving
• Robust protection including 7.5 kV HBM ESD and IEC61000-4-5 2 kV surge immunity

Analog Front End (AFE) Applications

• Programmable logic controllers (PLCs)
• Industrial automation and process control systems
• High-precision data acquisition modules

Analog Front End (AFE) Procurement Notes

Verify the ordering suffix 'K' indicates tray packaging containing 1300 units per tray. Confirm the specific part number matches the required 4-channel, 16-bit configuration. Ensure compatibility with the HVQFN64 package dimensions and thermal requirements for the target application design.

Analog Front End (AFE) Selection Notes

Select this model when four isolated channels are sufficient for the system architecture. The 16-bit resolution offers a balance between performance and power consumption compared to 24-bit variants. Verify that the integrated excitation sources meet the drive requirements for connected sensors such as RTDs or strain gauges without external amplification.

Analog Front End (AFE) Part Context

This component belongs to the NXP NAFE family of highly configurable analog front-ends. It shares pinout and software compatibility with other family members like the NAFE13388 and NAFE13188, allowing for scalable designs across different channel counts and resolution requirements within the same hardware platform.

Analog Front End (AFE) Replacement Considerations

Direct replacements include NAFE13144B40BS and NAFE13144B40BSE, which share identical electrical specifications but differ in packaging format. Cross-family substitution with NAFE13184B40BS requires verification of channel count differences.
