Other Parts Discussed in Thread: TMS570LS3137
Hello.
I have refered datasheet of TMS570LS3137.
spns162a:
(P38) 3.1 Absolute Maximum Ratings Over Operating Free-Air Temperature Range,
Input voltage range: ADC input pins .. -0.3 V to 5 V
On absolute maximum ratings, ADC input pins is -0.3V to 5V.
But, it seems that the AVI(Analog input voltage) is allowed up to MAX 5.25V.
spns162a: (P117) 5.2.3 ADC Electrical and Timing Specifications
VAI: Analog input voltage .. ADREFLO[MIN] ADREFHI[MAX] V
※ ADREFHI: A-to-D high-voltage reference source .. ADREFLO[MIN] VCCAD[MAX] V
VCCAD: MibADC supply voltage .. 3[MIN] 3.3[NOM] 3.6[MAX] V
4.5[MIN] 5.0[NOM] 5.25[MAX] V
- How do you think about this?
- Is the ADC input pin allowed voltage between 5V and 5.25V?
Best regards, RY
