May I know the ADC reference voltage of LTC2990
I'm using a couple LTC2990 parts and just realized I connected the polarity for V3 and V4 back wards. i.e the chip wants to subtract V3 from v4 meaning V3 should be a greater value than V4. In my case V4 is a greater value then v3. When I configure the…
I am going to use LTC2990 for current measurement.
May I know how to calibrate the ADC inside LTC2990.
Hi all - I have uploaded a C++ driver for the LTC 2990 power monitor on GitHub but I do not know whom to contact at Analog. This is an I2C driver for the Raspberry Pi, for this device, if anyone is interested in such.
A wonderful IC. I will also be posting…
There is currently an error in the datasheet regarding current measurements. The updated version should be releasing soon. Please refer to https://ez.analog.com/energy-metering/f/q-a/103424/equations-to-convert-the-register-values-to-current…
May I know from where you get the value .75 for RMS noise.
I am using LTC2990 to measure the current, i got a question:
while i used the differential mode, got the value of sign =1 ,and D[14:0] = 7FE5, so the Vdiffer=-27*19.42= -524 uV,
the R rense Value is 30 mΩ, in my opinion, the current…
