SLDS204B October 2014 – June 2020 PGA300
PRODUCTION DATA.
The PGA300 implements the diagnostics described in Table 6.
DIAGNOSTICS DESCRIPTION | ACTION |
---|---|
Execution-timing error | DAC is disabled and digital compensation logic set to a reset state |
Checksum error of internal logic | DAC is disabled and digital compensation logic set to a reset state |
EEPROM is corrupted or EEPROM CRC_GOOD = 0b0 | DAC code is driven to 0 code |
Power-supply and signal-chain errors | DAC output is driven to the value determined by the DAC_FAULT_LSB and DAC_FAULT_MSB registers |
All the foregoing diagnostics are enabled by setting the DIAG_ENABLE bit in the DIAG_ENABLE register. To disable diagnostics, set the DIAG_ENABLE bit to 0b0.
