INA138: INA138 - BOM resistor error in TIDU833

Andras Magyar

Part Number: INA138

Dear Experts,

I am designing with INA138 and I found an error in the high common mode design document:

https://www.ti.com/lit/ug/tidu833/tidu833.pdf?ts=1674152579656&ref_url=https%253A%252F%252Fwww.google.com%252F

On page 14 in the A.2 Bills of Materials table the 200k (R1) resistor Manufacturer Part Number is wrong as it indicates a 1 Ohm resistor instead of a 200k one.

Alternative part number is fine.

Regards,

Andras

Hi Kai,

Also on the same page on the INA138 schematic the +VIN and+V pins are swapped.

Hi Andras,

the problem with writing appnotes and datasheets is that you become routine-blinded and begin to overlook the mistakes over and over again. The only remedy is to use the method of crosschecking: Another person which was not invloved in writing the document and is assuming the role of the user carefully reads through the whole document and makes corrections...
