Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The LTC2376IMS-20 is a low-noise, low-power, high-speed 20-bit successive approximation register (SAR) ADC with a ±VREF fully differential input range (VREF varies from 2.5V to 5.1V) from a single 2.5V operating supply. It consumes only 5.3mW of power and achieves ±2ppm INL (maximum), no missing codes (at 20 bits), and 104dB SNR.

The LTC2376IMS-20 features a high-speed SPI-compatible serial interface supporting 1.8V, 2.5V, 3.3V, and 5V logic, as well as a daisy-chained mode. 250ksps high throughput rate and no-cycle-delay characteristics make the LTC2376-20 ideal for many high-speed applications. An internal oscillator sets the conversion time, alleviating external timing considerations, and the LTC2376-20 automatically powers down between conversion operations, reducing power consumption with sample rate.

The LTC2376IMS-20 provides a unique Digital Gain Compression (DGC) feature that eliminates negative power to the driver amplifier and maintains the full resolution of the ADC. When enabled, the ADC performs a digital scaling function that transforms the zero-scale code from 0V to 0.1-VREF and the full-scale code from VREF to 0.9-VREF. For a typical reference voltage of 5V, the full-scale input range is now 0.5V to 4.5V, which provides the ability to adjust the power consumption from a single 5.5V to 4.5V. For a typical reference voltage of 5V, the full-scale input range is now 0.5V to 4.5V, which provides enough room to power the driver amplifier from a single 5.5V supply.

• 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.
