Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The AD7927WYRUZ is a 12-bit, high-speed, low-power, 8-channel, successive-approximation ADC with a maximum throughput of 200 kSPS from a single 2.7 V to 5.25 V supply.The device has a built-in low-noise, wide-bandwidth sample-and-hold amplifier that handles input frequencies above 8 MHz.

The conversion process and the data acquisition process are controlled via CS and a serial clock signal, thus setting the stage for easy interfacing of the device with a microprocessor or DSP. The input signal is sampled on the falling edge of CS and the conversion is initiated here at the same time. The device has no pipeline delay.

The AD7927 uses advanced design techniques to achieve very low power consumption at the highest throughput. At maximum throughput, the AD7927 consumes a maximum of 1.2 mA with a 3 V supply and 1.5 mA with a 5 V supply.

The analogue input range of the device can be selected between 0 V to REFIN or 0 V to 2 × REFIN by configuring the control registers with standard binary or binary-complement output encoding.The AD7927 has eight single-ended analogue inputs with channel sequencers, and the order of the channel conversions can be selected by pre-programming.

The conversion time of the AD7927 is dependent on the SCLK frequency, which is also used as the master clock for conversion control, and can be reduced to 800 ns at an SCLK frequency of 20 MHz.

• 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.
