Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

MAXM86161EFD+T is an ultra-low power, fully integrated, optical data acquisition system. On the transmitter side, the MAXM86161 has 3 programmable high current LED drivers. On the receiver side, the device contains an efficient PIN photodiode and an optical reading channel. The optical readout channel has a low noise signal conditioning analog front end (AFE) that includes a 19-bit ADC, an industry-leading ambient light offset (ALC) circuit, and fence detection and replacement algorithms. With its low power consumption, compact size, ease of use/flexibility, and industry-leading ambient light suppression capabilities, the MAXM86161 is ideal for a wide range of light detection applications, such as heart rate detection and blood oxygen.

Advantages and characteristics:

Complete single channel, optical data acquisition system

Built-in algorithms are further enhanced to suppress fast environmental transients

The structure is optimized for reflex heart rate and SpO2 monitoring

Low dark current noise: < 50pA RMS (sampling to sampling difference)

Lower effective dark current noise can be achieved through multiple sampling modes and on-chip averaging

• 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.
