Hello Mirko,
Thanks for choosing to use Texas Instruments in your design. Kai raises a valid point as the INA138 is a unidirectional device that will only measure the forward current. If you want to measure a bidirectional signal, you will need to use…
Other Parts Discussed in Thread: INA170 In my application, I am using multiple triacs to switch on/off multiple solenoids. The solenoids are supplied by 24VAC. I need to accomplish two things: 1) Detect a fault condition with the solenoid, i.e. a short…
Other Parts Discussed in Thread: INA199 , INA138 , INA139 , INA170 , INA169 , INA168 , INA223 , INA225 , LMP8640 The default gain of the INA199A3 is 200. Can I add two resistors to the inputs (IN+, IN-) of the op-amp to lower the gain? For example adding 3K3 resistors…
Hello Ramakrishna,
It appears as though you have submitted 3 separate high-side current sensing applications questions. They all appear to be very similar with the exception of the common-mode voltage and maximum current. Next time it may be more effective…
I am using the AnalogOut pin on mbed with Cortex-M3 to control the input to the current transmitter. There is an embedded system running Linux that is connected via internet to our server.
