Part Number:INA271
Hello guys,
One of our customers is evaluating INA271 now. Their evaluation circuit is almost same as the simplified schematic on page 1 in the device datasheet (SBOS381E). But one point is different from the schematic. it is that a relay has been inserted between the -16V to +80V supply and IN+ terminal and between IN- terminal and Load.
When those relay were off (opened) and INA271 was powered on with 5V , they found about 1V was observed on IN+ terminal.
Is this a normal operation? Also they would like to know why about 1V is observed on IN+.
Could you please give me any reply?
Your reply would be much appreciated.
Best regards,
Kazuya Nakai.
