MLT04 analog multiplier. Offset trouble

Jan 23, 2006 1 Replies

I'm having trouble using the MLT04 analog multiplier. When I measure the output from the multiplier I get a drifting offset. The offset drifts with a low frequency about 1-2 mV.



I have grounded the inputs to the multiplier to see if the offset drift came from there, but there's no difference.



Anybody having the same experience with this part?



The spec sheet claims 0.005%/degree centigrade drift. If the temperature chages 1 degree C, I think that means the offset might drift 10 volts * 0.00005 = 0.5 millivolt. Maybe you part is undergoing a 2 to 4 degree temperature change?

Dont' feel too bad, the older multipliers were several powers of ten worse.
