Other Parts Discussed in Thread: LMP8645 , TINA-TI , LMP8646 Hello,
I want to simulate LMP8645 (current sensing amplifier) using TI Tina. In the datasheet it states that SNOM087 is the Tina spice model, but I cannot find the model from Tina. Can you…
Other Parts Discussed in Thread: LMP8645 , LMP8640 Hello,
I'm unsuccessfully using an LMP8645 to current sense on the high side of a DC circuit. I'm supplying an amplifier with 12V DC whose current draw range is 60±10mA. I'm interested in monitoring…
Other Parts Discussed in Thread: LMP8645 Hello,
Currently we are evaluating the LMP8645 as a current monitor, so far the IC performs quite good but we have a question.
Since the IC seems to be very accurate we want to sue it to measure voltage as…
Part Number: INA270 Other Parts Discussed in Thread: LMP8278Q-Q1 , INA138 , LMP8645 Hi team, My customer is currently using the AD8208 for high-side current sensing and feeding its output into a 5V microcontroller. However, they are planning to switch…
Part Number: INA213 Other Parts Discussed in Thread: INA791 , LMP8646 , LMP8645 Tool/software: Dear TI Engineer,
I hope this email finds you well. I am a circuit design engineer working with the INA213, and I have a few questions regarding this chip…
Hi Lenio,
No model was made for the LMP8640, but one does exist for the LMP8645. These devices are very similar, so I can spin the LMP8640 model fairly quickly. I'll plan to get this done by next Friday, 2/22.
Best regards,
Ian Williams
Other Parts Discussed in Thread: LMP8645 Hello,
I am trying to determine whether current limiting resistors are needed between LMP8645MKE and TM4C129XNCZADI3R. For my design the voltage on Pin 1 (Vout) of LMP8645 is measured and converted by the MCU…
Hello Ganesh,
Thank you for using the TI forum. I have a few questions for you.
Have you tried testing the gain with only a DC signal? If so, do you still have gain problems?
Try measuring the voltage differential right at the IN+ and IN- pins…
