Need to identify a component
« on: July 14, 2017, 07:06:55 am »
Hi and good day!

Does anybody know what the component (SO-8 package) has a "TFT    3M0033" marking on its package (a photo is attached) ?
For a first approach, it may be a precision resistors network - the component is installed in the wheatstone bridge measurement unit. But I could not find it in any catalogue...

Thanks in advance!

Could be an instrumentation amplifier. Is it connected to any balanced power supply? Trace the pins. Example trace Pin 7 and Pin 4.

Thank you, guys.

This IC is a passive component: it is not powered, but it's installed in the signal chain. Checking with a ohm-meter showed that a resistor matrix inside (seems, it is a custom layout Thin Film Technology product).
