NXP N-AFE 8-Channel Analog Front-End IC

NXP N-AFE 8-Channel Analog Front-End IC
NXP N-AFE 8-Channel Analog Front End (AFE) IC is a highly configurable industrial-grade multi-channel general-purpose input AFE for high-precision measurement requirements. These devices integrate a low leakage, high voltage (HV) fast multiplexer, low offset/low drift programmable gain amplifier (PGA) and buffer, high data rate 24-bit Delta-Sigma analog-to-digital converter (ADC) and Low Drift Voltage Reference. The NAFE11388 and NAFE71388 ICs are equipped with various diagnostic and power monitoring circuits for status monitoring and abnormality detection. Two precisely calibrated voltage sources simplify end-to-end system self-calibration and predictive maintenance. Applications include programmable logic controllers (PLCs), I/O modules, data loggers, instrumentation, and high precision sensor/data acquisition systems.
