Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The LTC2688IUJ-16 is a 16-channel, 16-bit, ±15 V digital-to-analog converter (DAC) with an integrated precision reference voltage source.The LTC2688IUJ-16 is guaranteed to be monotonic and has a built-in rail-to-rail output buffer that can supply or sink up to 20 mA of current.The SoftSpan™ DACs offer five output ranges up to ±15 V. Each range is independently programmable. Each channel's range is independently programmable.

An internal 4.096 V precision reference voltage source sets the accuracy of the output voltage. An external reference voltage source is available for additional range options. Three toggle pins support input register A and input register B switching or sinusoidal dithering at multiple frequencies. Analogue multiplexer simplifies measurement of pin voltages, load currents and junction temperatures.

Programmable offset and gain registers improve the accuracy of the DAC output.

Serial Peripheral Interface (SPI) and MICROWIRE™-compatible 3-wire serial interface operate at logic levels as low as 1.71 V and clock rates up to 50 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.
