Hi,

Could you tell me about INA2128 supply current?
I want to know the maximum current consumption to choose the power supply for INA2128.
The following contents are described in the data sheet.
May I consider 1.5mA the worst case?

Use condition is
Supply voltage : ±6V
Gain : 1.4
Input voltage : ±2.5V

Could you give me your advice?

Best regards,
Yusuke

Including this thread we received three identical questions on this specification, so I assume there is a common source. Kai answered the question in the thread he referenced above, but to reiterate the maximum current consumption of this part will be the maximum quiescent current (1.5mA) plus the maximum load current.

Regards
Dennis
