NAFE13388 Datasheet | NXP Semiconductors

description The NAFE13388 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 low-drift programmable gain amplifier (PGA) and buffers, high data-rate 24bit sigma-delta analog-to-digital converter (ADC), precise voltage and current excitation source, and low-drift voltage reference. All of the HV analog pins are diode-protected internally for electromagnetic patibility (EMC) and miswiring scenarios. The NAFE13388 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 NAFE13388 family of products is designed for programmable logic controllers (PLCs), I/O modules, data loggers, instrumentation, and high-precision sensor and data acquisition systems.
