Part Number: INA280-Q1 Hi.,
In one of our motor controller project, using current sense IC -Part Number- INA280A2QDCKRQ1.
With this current sense IC, we are using 1mOhm/5W shunt resistor for measuring 60A current flowing through supply voltage.
The problem…
Part Number: INA280 Other Parts Discussed in Thread: INA240 Hello everyone,
I am trying to measure the current of a peltier cell that I am controlling with an h-bridge and a PWM signal. I control the duty cycle of the PWM to control the voltage in the peltier…
Part Number: INA280 Hello,
Please tell me about the Analog Inputs, VIN+ and VIN- parameters in 6.1 Absolute Maximum Ratings in the INA280 data sheet. Do the following items apply even when the power between VS and GND is not up (0V between VS and GND)…
Part Number: INA280 Other Parts Discussed in Thread: TPS2660 , INA303 , INA302 , INA301 , INA381 Support Team,
Below is our current configuration of the design. Since TPS2660 current measurement has 8.5% tolerance we are planning to implement INA280 externally…
Part Number: INA280 Other Parts Discussed in Thread: TINA-TI , Hello,
The customer will use the INA280A2. The customer has reviewed Table 8-1. RSENSE Selection and Power Dissipation in the datasheet. The customer is concerned about the item 8.2.2.1 Overload…
Part Number: INA280 Hello,
Spice model has an error:

Part Number: INA280 Other Parts Discussed in Thread: INA281 Hi team,
I used INA280A1 to test inductor current as below buck circuit. I used 100mΩ shunt resistor to test the tringle current (green one), its frequency is 20kHz, peak value is 1400mA, and…
Part Number: INA280 Hello,
I would like to know, what could happen, if the 3.3V supply for INA280 is missing, but IN+ and/or IN- has voltage?
I am looking forward to your answer!
Thank you and best regards,
Ziming
Part Number: INA280 Hello Team,
due to cable length between the end device and the output of the INA280, we are considering adding a filter on the output.
In particular as shown in the picture
the first RC is 100R 100pf, the other RC 1K 10n.
this opens…
Part Number: INA280 Hi team,
I got a question form customer that is there any potential issue having INA280 (or similar current sense amplifier) connected to power part of the circuit (to VCM) but with +5V (Vs) disconnected? The application is permanently…
