2. Introduction

The LTC2321HUFD-16 is a low-noise, high-speed, dual-channel 16-bit successive approximation register (SAR) ADC with differential input and wide input common-mode range. The LTC2321-16 adopts a single 3.3V or 5V working power supply and has an 8VP-P differential input range, making it highly suitable for applications that require a wide dynamic range and high common-mode suppression. The LTC2321HUFD-16 achieves ±4LSB INL (typical value), no missed codes (in 16 bits), and 81dB SNR.

3. Application fields

The LTC2321HUFD-16 device is suitable for various application scenarios that require high speed, high precision and wide dynamic range, such as communication, industrial control, test and measurement, etc. Its low noise and wide input common-mode range make it outstanding in applications that require high common-mode suppression ‌.

• 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.
