NAFE11388B40BSMP

NAFE11388B40BSMP is a highly configurable industrial-grade multichannel universal input analogue 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 24-bit Delta-Sigma analogue-to-digital converter (ADC), and low-drift voltage reference. All of the HV analogue pins are diode-protected internally for electromagnetic compatibility (EMC) and miswiring scenarios. The NAFE11388 is equipped with various diagnostic and supplies supervisory circuitry for condition monitoring and anomaly detection. The NAFE11388 family of products is designed for programmable logic controllers (PLCs), I/O modules, data loggers, instrumentation, and high-precision sensor and data acquisition systems.
