NAFE11388规格书详情
1 General description
The NAFE11388 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 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 NAFE11388
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 selfcalibration
and predictive maintenance.
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.
