NAFE93352B40BSMP

Analog Front End (AFE) Overview

The NAFE93352B40BSMP is a high-speed, universal fully configurable analog input and output analog front end (AIO-AFE) from NXP. It integrates one software-configurable AIO channel and two universal input channels within a compact 6mm x 6mm TQFN-40 package. The device features a precision DAC with up to 18-bit resolution and an ADC with up to 24-bit resolution. Operating at data rates up to 200 ksps for the DAC and 576 ksps for the ADC, it supports supply voltages from ±7V to ±28V. Accuracy reaches ±0.01% at room temperature and ±0.08% over the full -40°C to 125°C range after calibration.

Analog Front End (AFE) Feature Summary

• High-speed performance: DAC up to 200 ksps, ADC up to 576 ksps
• Universal I/O configuration: One configurable AIO channel plus two universal inputs supporting ±12.5V, ±25mA, and resistance measurements
• High precision: 18-bit DAC and 24-bit ADC options with ±0.08% accuracy over temperature
• Robust protection: ±36V protected I/O with short-circuit protection on both inputs and outputs

Analog Front End (AFE) Applications

• Programmable Logic Controllers (PLC)
• Process Control Systems
• Industrial I/O Modules
• Data Loggers

Analog Front End (AFE) Procurement Notes

Verify the specific suffix B40BSMP against the official datasheet to confirm pinout, packaging, and calibration status. Ensure external transient voltage suppressors are included in the design for output channels to meet the ±36V protection specification. Confirm compliance with SafeAssure functional safety requirements if applicable to the target system.

Analog Front End (AFE) Selection Notes

Select the NAFE93352 variant over the NAFE33352 when higher throughput is required, as this model supports up to 576 ksps ADC and 200 ksps DAC speeds. Consider the 24-bit ADC resolution for high-precision measurement applications. Verify that the system can accommodate the ±7V to ±28V supply voltage range and the 6mm x 6mm TQFN-40 footprint constraints.

Analog Front End (AFE) Part Context

This component belongs to the NAFEx3352 family of Universal Fully Configurable Analog Front Ends. It serves as the high-speed counterpart to the low-power NAFE33352, offering enhanced data conversion rates while maintaining the same universal channel architecture and compact form factor designed for industrial automation and process control environments.

Analog Front End (AFE) Replacement Considerations

The NAFE33352 is a related family member but offers lower data rates (max 288 ksps ADC). No direct public substitute part numbers are identified in the provided documentation.
