INA105: INA105 - Application note for Figure 5

Srikanth Kacchu1

Part Number: INA105
Other Parts Discussed in Thread: TINA-TI

Hi Team

We are using INA105 in one of our design. We have followed the configuration shown in Figure 5 of datasheet (SBOS105) with different V- and 500 ohm instead of 100 ohm.

We need to understand the output voltage derivation. Pls provide any application if available.

Hi Srikanth,

why not running a TINA-TI simulation with the

INA105 TINA-TI Reference Design (Rev. B)

TINA-TI is super simple to use, is free and can be downloaded here:

Hi Srikanth,

Page 24 in this application document discusses the current receiver with compliance to both power supply rails using the INA105.

In addition I was going to suggest that we run a Tina simulation to help you understand the transfer function as Kai suggested. If you would like to provide a schematic I can put together a simulation using your values and voltage condition. Let me know if I can be of further assistance.

Best Regards,

Chris Featherstone
