Hello,
I would like you to confirm about below.
* When user want to input -2.048V to 2.048V to ADC as single end signal without negative reference source, Is following configuration available ?
AVDD1 = AVDD2 = 2.5V
AVSS = -2.5V
DGND = 0V
VREFP = 2.048V
VREFN = 0V
VINP = -2.048 to 2.048V (0V center)
VINN = 0V
("INP_RNG" bit should be set to "2x input range").
If this setting is available, which point should user connect VREFN and VINN ?
(VREFN and VINN are just connected to analog ground ? )
BR,
