NAFE13148B40BSE

Analog Front End (AFE) Overview

The NAFE13148B40BSE 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. Packaged in a 64-pin HVQFN, it operates within a temperature range of -40 °C to +125 °C.

Analog Front End (AFE) Procurement Notes

Verify the specific ordering suffix B40BSE against the manufacturer's official documentation to confirm packaging details and availability status. Ensure compliance with RoHS requirements and check for any regional distribution restrictions before procurement.

Analog Front End (AFE) Selection Notes

Select this part for applications requiring 16-bit resolution and low-power operation. It is suitable for designs needing integrated excitation sources but does not require factory calibration coefficients. Compare performance metrics against the NAFE13388 if higher accuracy or 24-bit resolution is necessary.

Analog Front End (AFE) Part Context

This component belongs to the NAFE13388 family of universal input analog front-ends. It shares pinout and software compatibility with other family members like the NAFE13188 and NAFE13144, allowing for scalable design implementations across different channel counts and resolution requirements.

Analog Front End (AFE) Replacement Considerations

Direct substitutes within the same family include NAFE13144B40BSE for 4-channel configurations. For higher precision needs, consider the NAFE13388B40BSE. Verify pin compatibility and register settings when migrating between variants.
