NAFE13388B40BSMP

NAFE13388B40BSMP is a NAFE13388 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 24/16bit sigma-delta analogue-to-digital converter (ADC), precise voltage and current excitation source, and low-drift voltage reference. All of the HV analogue pins are diode-protected internally for electromagnetic compatibility (EMC) and miswiring scenarios. It is designed for programmable logic controllers (PLCs), DCS I/O modules, I/O modules, data loggers, instrumentation, industrial automation and process control and high-precision sensor and data acquisition systems.
