Hello Darko,
Thank you for your interest in Texas Instruments' INA3221. We do not believe it is good practice for you to power INA3221 below the specified +2.7V. The device you have now may work with a 2.3V supply, however we expect that if you purchased…
Hi Mayrim,
Sorry, I make a mistake. The IC number is INA216. Can INA216 be used for the low-side? If not, why?
Which component can be used for thelow-side ?
Other Parts Discussed in Thread: INA216 , TINA-TI , INA216EVM Hi,
I implemented an input bias current simulation for INA216 with TINA-TI. Though I have assumed that an input bias current is 3uA, the result was about 16uA as attached. Please let me know what…
Other Parts Discussed in Thread: INA216 Hi,
today I noticed that both my SmartRF06 boards don't have the current measurement circuit mounted. On the User’s Guide (SWRU321A) it is stated that the board has a circuit for high side current measurement…
Other Parts Discussed in Thread: INA216 I have bought the SmartRF06EB and CC1310EM, when I tried to measure the current of the EM, I found the TP11 has no signal at all. Carefully looked the board I found the U504(INA216 is not loaded. I wonder why?
Dear Kuramochi,
I am looking at this with my team right now and will get back to you with a recommendation. Thank you for all of your information.
What is the common-mode voltage (Vcm) of your system? Basically since this is a high-side application, what…
Other Parts Discussed in Thread: TPS60241 , BQ27425-G2A , INA216 Dear Specialists,
My customer is looking for substitute of MAX3355E.
MAX 3355E is Charge Pump for USB On-the Go, included VBUS comparator and status output.
I can't find the device included…
I find that there is no INA216 on SmartRF06EB with rev:1.2.2 but I can see INA216 on SmartRF06EB with rev:1.2.1. So, I can use TP11 the measure current consumption on SmartRF06EB with rev:1.2.1 but it would fail on SmartRF06EB with rev:1.2.2. If you use…
Hello Jan,
The INA216 is a current shunt monitor, which typically have more input bias current than instrumentation amplifiers. If you're trying to measure 1uA, the INA216 will not work because the input bias current is 3uA. The INA333, however, has…
Other Parts Discussed in Thread: INA193 , INA194 , INA216 , INA118 , TINA-TI , INA210 , PGA280 , INA333 Hi,
I have been measuring the energy consumption of some smartphones using a shunt resistor, but now I would like to add a shunt monitor (unidirectional is…
