General description
The NAFE71388 is a highly configurable industrial-grade multichannel universal input
analog front-end (AFE) that meets high-precision measurement requirements. The
device integrates low-leakage, high-voltage (HV) fast multiplexers, low-offset and lowdrift
programmable gain amplifier (PGA) and buffers, high data-rate 24-bit Delta-Sigma
analog-to-digital converter (ADC), and low-drift voltage reference. All of the HV analog
pins are diode-protected internally for electromagnetic compatibility (EMC) and miswiring
scenarios. The NAFE71388 is equipped with various diagnostic and supplies supervisory
circuitry for condition monitoring and anomaly detection. Two precise calibration voltage
sources are made available for ease of end-to-end system self-calibration and predictive
maintenance.
The NAFE71388 family of products is designed for programmable logic controllers
(PLCs), I/O modules, data loggers, instrumentation, and high-precision sensor and data
acquisition systems.
