Part Number: LMP8603-Q1 Hello,
I would like to use the LMP8603-Q1 current sense amplifier in a system which has a variable current range (0~25mA, -1.5A~1.5A). I would like to use the ability to reduce the gain by switching in the resistor from A1/A2…
Part Number: LMP8603 Other Parts Discussed in Thread: INA286 , INA240 , INA270 Hi Team,
I am looking for a pin compatible LMP8603 (VSSOP package) device with the same internal 2 nd order filter, but with much better CMRR figures like for the INA240…
Part Number: LMP8603 Other Parts Discussed in Thread: TINA-TI Hello,
We have designed in the LMP8603 and are currently in developmental test of engineering model units of our PCBs. The LMP8603 circuitry does not seem to be working according to the spec…
Thank you Javier for confirming this
My application is fairly simple and straightforward - at least I hope so...
I plan to use the LMP8603 (Gain-100) to monitor a current flowing from the device to an external negative power supply. The negative…
Part Number: LMP8603-Q1 Other Parts Discussed in Thread: LMP8601-Q1 , LMP8601 , LMP8602-Q1 , LMP8602 , LMP8603 , Hi,
I am planning to use this part to monitor the current flowing into a negative power supply. While reading the datasheet, I am a bit…
Hello Nobuo,
As the lmp8603-q1 uses the same architecture as the lmp8601 I tested in that previous post, you will not be able to adjust the gain. I verified on the bench with LMP8603 that you will not be able to get a meaningful measurement with the…
Satoshi,
The configuration on page 23 of the datasheet (also shown below) is for reducing the gain. The default gain of the LMP8603 is 100V/V. Any resistor tied to A1, A2, and ground like in the figure below, will lower the voltage at A2 and the overall…
Part Number: LMP8603 Hello,
I'm going to use the LMP8603 ( i.e. nominal gain of 100 ) with external feedback resistor to increase the gain up to a total of x500. I'm using 5V supply. The nominal current to be detected will provide a voltage output between…
Other Parts Discussed in Thread: LMP8603 Hello
I have an application of LMP8603 amplifying a low side 2mOhm shunt, with 3.3V supply
Offset is biased at the half of the ADC reference voltage (typ 2.44V) through a buffer amplifier as required by datasheet…
Hello Hideyuki,
It is possible to route the signal directly between A1 and A2... there is no problem with that.
Adding the capacitor, as mentioned in the datasheet, introduces a low-pass filter in combination with the internal 100k ohm resistor. In…
