NAFE93352B40BSK

Analog Front End (AFE) Overview

The NAFE93352B40BSK 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 high-speed DAC with data rates up to 200 ksps and an ADC supporting rates from 15 to 576 ksps. It operates on supply voltages ranging from ±7V to ±28V and maintains accuracy of ±0.01% at room temperature and ±0.08% over the full -40°C to 125°C temperature range after calibration.

• Industrial I/O Modules
• Data Loggers

Analog Front End (AFE) Procurement Notes

Verify the specific suffix B40BSK against the official datasheet to confirm pinout, packaging, and calibration status. Ensure external transient voltage suppressors are included in the design for output protection as required by the ±36V 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, specifically for ADC rates exceeding 288 ksps or DAC rates above 100 ksps. This component is suitable for applications demanding high-resolution data acquisition (up to 24-bit ADC) and precise control (up to 18-bit DAC) in space-constrained industrial environments.

Analog Front End (AFE) Part Context

This part 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 speeds while maintaining the same compact footprint and universal channel flexibility for industrial automation and process control applications.

Analog Front End (AFE) Replacement Considerations

The NAFE33352 is a related low-power variant within the same family but offers reduced maximum data rates (DAC 100 ksps, ADC 288 ksps). Direct substitution requires verifying that the lower speed specifications meet the application's timing requirements.
