General description

NAFE11388 is a highly configurable industrial grade multi-channel universal input Analog

Front-End (AFE) that meets high-precision measurement requirements. The device

integrates low-leakage high-voltage fast multiplexers, low offset and low drift PGA and

buffers, a precision and high data rate 24-bit Delta Sigma ADC and a low-drift voltage

reference. The analog high voltage (HV) input pins are diode-protected internally for EMC and wire misuse scenarios; NAFE11388 is equipped with diagnostic circuits for functional safety, condition monitoring and fault detection. Two precise voltage sources are made available for end-to-end system self-calibration and anomaly detection for predictive maintenance. NAFE11388 is designed to be used in programmable logic controllers (PLC), I/O modules, data loggers, instrumentation, high precision sensors and data acquisition systems.
