HI
Quick question:
Just wondering what the maximum negative input voltage that could be applied to the ADC inputs of the TMS320F2808?
Assume that all input are have clamp diodes to +/- to supply rail and 0VD of the uP?
Thanks
Regards
Colin

Colin,
The absolute max is listed in the datasheet here: http://www.ti.com/document-viewer/TMS320F2808/datasheet/absolute-maximum-ratings-idncixz382sylv#IDNCIxz382sylv negative max is -0.3V
You are correct there are ESD clamping diodes built into the device, the max cumulative clamping current allowed is +/-20mA total and +/-2mA per pin.
Best,
Matthew
