Instructions:

The NAFE11348B40BSMP is a highly configurable, industrial-grade 8-channel universal Input Analog Front end (AFE) family that meets high precision measurement requirements. The device integrates a low leakage high voltage (HV) fast multiplexer, a low offset/drift programmable gain amplifier (PGA) and buffer, a high data rate 16-bit Delta-σ analog-to-digital converter (ADC), and a low drift voltage reference.


The device is equipped with a variety of diagnostic and power supply monitoring circuits for condition monitoring and anomaly detection. To facilitate end-to-end system self-calibration and predictive maintenance, two precise calibration voltage sources are provided.

NAFE11348B40BSMP is designed for low power applications.
