Other Parts Discussed in Thread: INA128, INA126, TINA-TI
Hi, I am using INA128 in a circuit for amplification. IC seems to be working fine on the board without any issues till date. I have problem with LT spice simulation of the circuit. I am using the INA128.LIB in my simulation and it doesn't work as expected. It is not doing Gain*(Vinp-Vinn) in the simulation. Whatever may be the inputs, i always see the output stuck at around -4V. When I used INA126 spice model in the same circuit, it works fine but INA128 doesn't work. Can anyone help in this regards.
