Package Options

The AD7683 comes in two different types of packages: an 8-lead Mini Small Outline Package (MSOP) and an 8-lead Quad Flat No-Lead (QFN) Lead Frame Chip-Scale Package (LFCSP).

8-lead MSOP

  • The MSOP package is small and has a low profile, so it can be used in applications with limited room.
  • Its small size makes it easy to put into systems with small circuit boards.
  • Most of the time, the MSOP package works well with heat and is easy to solder onto the PCB.
  • It is often used in portable electronics, market electronics, and other places where size and weight are important.

8-lead QFN LFCSP

  • The QFN LFCSP package uses the advantages of a Quad Flat No-Lead package and the technology of a Lead Frame Chip-Scale Package.
  • The QFN package has good thermal performance, so it can get rid of heat quickly while it’s running.
  • It takes up less room on the PCB than other packages because it has a smaller footprint.
  • Because there are no leads, things like automatic optical inspection and X-ray inspection are easier.
  • The QFN package is good for applications that need to get rid of heat well, last a long time, and be strong.
  • It is often used in industrial uses, electronics for cars, communication systems, and designs with a high number of parts.

Operating Temperature Range

  • The AD7683 is made to work in a range of temperatures from -40°C to +85°C. Because the ADC can work in such a wide range of temperatures, it can be used in tough industrial settings and places with extreme weather. The AD7683 is versatile and can be used in a wide range of situations because it can work successfully at both low and high temperatures.
  • The AD7683 comes in both an 8-lead MSOP package and an 8-lead QFN LFCSP package. The MSOP package is small and good for applications with limited room, while the QFN LFCSP package is strong and has good thermal performance. Also, the ADC can work in temperatures from -40°C to +85°C, which makes it suitable for many different settings and gives it more uses.
