ADC: ADC-C Does Not Meet 16-bit Mode Specifications

Revisions Affected

0

Details

ADC-C does not meet 16-bit mode specifications; but ADC-C does meet 12-bit specifications.

ADC-A and ADC-B meet 12-bit and 16-bit specifications.

Workaround

If the application requires ADC-C to be used in 16-bit mode, performance will be degraded. Use one of the following workarounds:

  • Operate ADC-C at a lower frequency of 44 MHz to meet specifications.
  • Use ADC-C in 12-bit mode without having to lower the operating frequency.

To satisfy synchronous conversion requirements if more than one ADC is used, see the Ensuring Synchronous Operation section of the TMS320F28P65x Real-Time Microcontrollers Technical Reference Manual.
