6.3 Modifying Hardware and Using Software to Evaluate Other Devices in the Family

The ADS8555 is part of a family of related devices. This EVM hardware and software support the entire family
because all the devices are pin-for-pin compatible. The
following procedure shows how to modify the hardware and software to evaluate the other devices in this family.
1. Desolder the ADS8555 and replace this device with the device you want to evaluate.
2. Enable the EEPROM for writing. This process is done by changing switch S2 to the WR_EN (top) position
using tweezers. Figure 6-3
3. Connect the EVM and start the GUI as described in
4. Under the Tools menu in
