Hi Sir,
the PCB has been return, but AMC60804 has no action(VDAC 1~4 no output, ADC 1 ~4 can not monitor).
1.could you help check if there is a problem with the schematic(as shown in the figure below), especially is PWSWN/ LDAC/ CLR/ Reset and / ALARM.
2. what setting do you think may affect this issue?
we hope that there is no need to set up monitor that can continuous read ADC and VDAC, IDAC.
the following the current setting of EML60804:
GEN_CFG (0x12) -> 0x0009
DAC_APD_EN (0x43) -> 0x0000
DAC_RANGE (0x40) -> 0x0005
ADC_GEN_CFG (0x40) -> 0x3336
in addition, before read any channel ADC each time, TRIGGER(0x10) will be set to 0x0001, and delay 1ms for reading.
we want to you confirm and help check whether there any problem with the ADC reading setting and process.
