INA240-Q1: Step Response

Part Number: INA240-Q1
Other Parts Discussed in Thread: INA240

Hello Team,

My customer is considering using INA240A1-Q1(Gain=20V/V) in automotive application and asked about step resopnse of INA240A1-Q1.
From the INA240-Q1 dathsheet, the step response plot (Figure 20) seem to be for INA240A4-Q1 because the gain seems to be 200V/V(10mVpp input signal, 2Vpp output signal). So mycustomer asked us to provide the INA240A1-Q1(20V/V)'s step response plots at the conditions as below.

1. Plot #1 when the input signal is 10mVpp
2. Plot #2 when the input signal is 100mVpp
3. INA240-Q1Test schematic of step response

Best regards,
DY

Hi DY,

I can certainly get these two plots for you with INA240A1-q1.

The setup will be: supply VS=5V; common mode Vcm=0V; REF1=REF2=0V. Please let me know if you want anything that is different than this.

Regards, Guang

Hi Guang,

My customer had asked us to provide the relevant step response plots for his input singal conditions (@ 10mVpp input signal, 100mVpp input signal). Can you provide the step response plots?

Best regards,
DY

Hi Guang,

Thanks for your quick response.

Would you please send me the TINA simulation file for INA240 reference design?
Because the INA240 TI-TINA reference design(Rev.A) can not open properly in the INA240 product folder as link below.
