NAFEx88 8通道類比前端IC

NXP Semiconductors NAFEx88 8-Channel Analog Front End (AFE) ICs are highly configurable industrial-grade 8-channel universal input ICs that meet high-precision measurement requirements. These AFE ICs integrate low-leakage, High-Voltage (HV) fast multiplexers, low-offset and low-drift Programmable Gain Amplifiers (PGA), and buffers. The NAFEx88 AFE ICs are equipped with various diagnostic and supply supervisory circuitry for condition monitoring and anomaly detection. These AFE ICs feature a high data-rate 24-bit Delta-Sigma Analog-to-Digital Converter (ADC), precise voltage and current excitation source, and low-drift voltage reference. The NAFEx88 AFE ICs provide two precise calibration voltage sources for ease of end-to-end system self-calibration and predictive maintenance.
