Hi,
I have a question about SD24_B input range.
Accoding to Absolute Maximam Ratings,
SD24_B input pins (SD0N0, SD0P0,SD1N0, SD1P0, SD2N0, SD2P0 -0.3V min ~ Vcc + 0.3V max
And 5.15 SD24_B specs ( Page 52 ),
Common-mode input voltage range AVSS – 1Vmin ~ AVCC max
I do not know why the common mode voltage exceeds the absolute maximum rating.
Can I use SD24 as a bipolar input?
Does this device have an attenuator in the input stage?
By the way, Our customer setup are below.
PGA Gain=1
AVCC = DVCC=3.3V, AVSS = DVSS = 0 V
SD0P0 = -900mV ~ +900mV (variable input voltage)
SD0N0 = 0V (fix)
Can we use in this condition?
I thought it was impossible.
Best regards,
Hiroshi
