Other Parts Discussed in Thread: INA170 Page 6 of INA170 datasheet, under OPERATION heading there are two equations. I want to know how to derive these two equations and I've tried them myself but cannot find a way to get the answer.
Can I please get…
Other Parts Discussed in Thread: INA170 The subject parts that we are receiving are marked "A70". Is this equivalent to "INA170 "? Is there a difference?
Thanks,

I'm having a similar problem. I am measuring current from a 12V battery, with V+ = 3.3V. The output voltage is not affected by the reference voltage at all. I'm putting a reference voltage on using the wiper of a 10k variable resistor (connected between…
Part Number: INA169 Other Parts Discussed in Thread: LMP8480 , , INA170 , LMP8481 , LMP8640HV , INA240 Hello Support,
I am investigating possible current sense solutions in our application. The input voltage is battery powered Vin: 10V ~ 40V and the continuous…
Hey Johanan,
Thanks for considering to use Texas Instruments. I suspect your issue stems from how you connected the device to the load. The INA138 is a unidirectional device, which means your current will need to flow from VIN+ to VIN- across your shunt…
Hi!
I have another question. If I use INA 170 instead of INA 136, will there be the above phenomenon? For example: If the detected current passes through the shunt resister and the corresponding voltage is -50 mv to +50 mv, the waveform is linear, then…
Lucas,
Thanks for using the forum. If you voltage is going above or below ground this will be difficult to do with our Current sense amplifiers that can only handle positive voltages at the inputs.
If it is only the current that is alternating then you…
Part Number: TPS53632G Other Parts Discussed in Thread: UCC27512 , LMG1205 , INA170 Hi !
I am building a GaN FET based half-bridge converter with the controller TPS53632G. The parameters are:
1. Input Voltage: Vin=36-75V DC
2. Output Voltage: Vout=28V

Hi George,
How is testing with this system going? If you are willing to consider a single-device solution, the INA170 is bipolar and functionally similar to the INA168. One of these can measure current in two directions with the usage of a reference pin…
