Other Parts Discussed in Thread: INA229
Hi, support team
My customer has the questions as follow:
I am thinking to use INA228 for VBUS voltage (max. 52V) and temperature measurement. Differential shunt voltage is not used.
1. Any other part numbers which may be more suitable for the above purpose?
2. For VBUS data accuracy, the datasheet lists the following but seems no specifications on reference and ADC accuracy. Are the specifications on reference and ADC accuracy available?
Vos_bus VBUS offset voltage
dVos/dT VBUS offset voltage drift
GBERR VBUS voltage gain error
GB_DRFT VBUS voltage gain error drift
3. How can I assess the accuracy of VBUS data? e.g. if VBUS is 52V, what is the error in the data from INA228?
Thanks so much.
Best regards,
Yuki
