Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The LTC2644CMS-L10 is a family of dual 10-bit PWM-to-voltage output DACs with an integrated high-accuracy, low-drift, 10 ppm/°C reference built into a 12-pin MSOP package. The devices feature rail-to-rail output buffers and are guaranteed monotonic.

The LTC2644CMS-L10 measures the PWM input signal and the period and pulse width, and updates the voltage output DAC after each corresponding PWM input rising edge. The DAC output is typically updated and stabilised to 12-bit accuracy in less than 8µs, and can supply and sink up to 5mA (3V) or 10mA (5V) of current to eliminate voltage ripple and replace slow-moving analogue filters and buffers. slow-moving analogue filters and buffer amplifiers.

The LTC2644CMS-L10 has a 2.5V fully scaled output with a 10ppm/°C internal reference. It can operate with an external reference that sets the full-scale output equal to the external reference voltage. Each DAC enters a pin-selectable idle state when the PWM input is held constant for more than 60ms. The device operates from a single 2.7V to 5.5V supply and supports PWM input voltages from 1.71V to 5.5V.

• 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.
