Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The LTC2358HLX-18 is an 18-bit, low noise, 8-channel simultaneous sampling successive approximation register (SAR) ADC with buffered differential, wide common mode range pA-level inputs. Featuring a 5V low voltage supply, flexible high voltage supply, and using internal references and buffers, each channel of the SoftSpan™ ADC can be independently configured in a "switch-by-switch" fashion to accept ±10.24V, 0V to 10.24V, ±5.12V, or 0V to 5.12V signals. signals. Additionally, individual channels can be deactivated to increase the throughput of the remaining channels.

The LTC2358HLX-18's integrated pA-level input analogue buffer, wide input common-mode range, and 128dB CMRR allow the ADC to directly digitise a wide range of signals with minimal board space and power. This input signal flexibility, combined with ±3.5LSB INL, no loss of code (at 18-bit), and 96.4dB SNR, makes the LTC2358-18 well suited for many high-voltage applications requiring wide dynamic range.

The LTC2358HLX-18 supports pin-selectable SPI CMOS (1.8V to 5V) and LVDS serial interfaces. One to eight data output channels can be used in CMOS mode, allowing the user to optimise bus width and throughput.

Test and measurement

• 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.
