Reference
The ADS8383EVM provide an onboard 4.096-V reference circuit. The EVM
also has the provision for users to supply a reference voltage via connecter P1
pin 20. This reference voltage may be filtered by installing amplifier U1. The
converter itself has onboard reference buffer, therefore it is not necessary to
buffer externally. The reference buffer circuit on the EVM is not populated with
an amplifier. The EVM allows users to select from two reference sources. Set
SJP1 and SJP2 to select onboard reference voltage (REF3040) or a
user-supplied reference voltage via P1 pin 20. See Table 22 for jumper
settings. See Chapter 6 for the full schematic.
