TMS320F280049C: CMPSS DAC output disturbance

Koichi Saito
Intellectual 2525 points

Part Number: TMS320F280049C

Hi Experts,

My customer is referring to TMS320F004x Datasheet (SPRS945F)
In 7.10.5.1.2 CMPSS DAC Static Electrical Characteristics, CPSS DAC Output disturbance is shown as -100LSB (MIN) and +100LSB (MAX).

Customer understands that the DAC output disturbance in CMPSS means a peak glitch voltage which is happened at MSB transitions (which graph is similar to Figure 7-44 and 7-45 shown for Buffered DAC).
Is that correct ?

If yes,
 - When DACVAL is changed from "1000 0000 0000" to "0111 1111 1111" 2048-to-2047, CMPSS DAC output disturbance is  -100LSB ?
 - When DACVAL is changed from "0111 1111 1111" to "1000 0000 0000" 2047-to-2048, CMPSS DAC output disturbance is +100LSB ?

Are these understandings correct ?
And also, the polarity of "+100LSB" and "-100LSB" above is correct ?

Best regards,
Saito
