Hi,
we are using the evaluation board ADA4254CP-EBZ for testing purpose. But after configuring board using SPI interface by
Arduino UNO board, we are not getting output as expected. Also while reading register values, getting "Input Amplifier Error" in analog error register.
As per datasheet, reason for this error is , " This flag indicates that one of the input amplifiers is
overloaded. The cause of this overload condition is either
saturation of one of the amplifier outputs, or a violation of the
input voltage range "
But the input voltage given is within the limit only. Anyone know, what is the reason for this error.??
OBSERVED DIIFERENTIAL output = 0 V
please find register read values for the reference as below,
GAIN_MUX : 0
SYNC_CFG : 4
DIGITAL_ERR : 0
ANALOG_ERR : 8A
GPIO_DATA : 0
INPUT_MUX : 60
WB_DETECT : 2
GPIO_DIR : 4
SCS : 0
ANALOG_ERR_DIS : 8A
DIGITAL_ERR_DIS : 20
SF_CFG : 4
ERR_CFG : 4
TEST_MUX : 50
EX_CURRENT_CFG : 0
