The NAFE73388B40BSK is a highly configurable, industrial-grade, multi-channel, general-purpose input analog front-end (AFE) that meets high-precision measurement requirements. The device integrates a low leakage high voltage (HV) fast multiplexer, low offset and low drift programmable gain amplifiers (PGAs) and buffers, a high data rate 24-bit Δ-∑ analogue-to-digital converter (ADC), accurate voltage and current excitation sources, and a low drift voltage reference. All high-voltage analogue pins are protected by internal diodes to prevent electromagnetic compatibility (EMC) and wiring errors.

The NAFE73388B40BSK is equipped with various diagnostic and power supply monitoring circuits for condition monitoring and anomaly detection. Two accurate calibration voltage sources are provided for end-to-end system self-calibration and predictive maintenance.

The NAFE73388B40BSK supports high speed data rates up to 576 kSPS. Designed for programmable logic controllers (PLCs), I/O modules, data loggers, instrumentation, and high-precision sensors and data acquisition systems.

• 1.Is the inventory and price seen on the platform accurate?

  A: all online goods on the shelves can be ordered online, but considering the large liquidity of spot inventory, it is not possible to achieve 100% accuracy at present. In case of any abnormality, you can contact our company online and give the corresponding solution.

• 2.Are all our products genuine?

  A: our self-supporting products are from cooperative domestic and foreign original factories or authorized agents, and the source can be traced to ensure the original and authentic products.

• 3.Can you provide the qualification certificate of the original factory or agent?

  A: at present, our self-employed brands TI，ST，ADI，NXP，LATTICE，CYPRESS，INFINEON，XILINX and other first-line brands. Other channels are the original factory and agency channels. If necessary, we can communicate and confirm according to the specific brand and model.

• 4.Can I make an inquiry through the company's website?

  A: You can inquire through the website, or by phone and email.

• 5.When can I deliver the goods after placing an order? How long will it take to get there?

  A: the delivery date is marked in most commodity information. You can estimate the delivery time of the commodity according to the delivery date. The specific arrival time depends on the warehouse where the commodity is located and the logistics mode you choose.

• 6.Can the company issue an invoice?

  A: you can issue ordinary invoices for individual users or special VAT invoices for enterprise users.
