28377S 12-bit ADC Modes

I would like to confirm whether or not the 28377S 12-bit ADC supports differential input?

There appears to be conflicting documentation in that regard.

Thank you.

  • Hi Justin,

    Yes, it very well does.

    Can you specify the same? Please refer the TRM of the device for the correct information.

  • Hi Justin,

    While it it true that the device can be put into 12-bit differential mode, this mode is unsupported and TI does not provide any electrical specifications for performance in this mode. There is also no test coverage for this mode during automated device production testing. The only supported modes are 12-bit single-ended and 16-bit differential.

    Practically, performance in 12-bit differential mode should give similar performance to 12-bit single-ended mode (but there is no guarantee of this performance or even correct functional operation on all devices).  

  • OK thanks. SPRUHX5A indicates only 12-bit single ended is supported.
