Transistor Level diagram LTC6430-20

Hi SaraPortero ,

Good day. Unfortunately, we can't share the transistor-level circuit of the part. May we know your application so we can help you further?

Sorry for the delay.

I'm attempting to use the amplifier to read a sensor differentially.

I wanted to know the structure to know whether or not it would have good common noise rejection ratio, without using the baluns.

If you have this information i would appreciate it.

 Hi SaraPortero ,

Good day. Unfortunately, there were no available documents discussing LTC6430-20 without the baluns. But based on the datasheet, the balun is only added in the test circuit to transform the LTC6430-20’s 100Ω differential source/load impedance to 50Ω single-ended impedance compatible with most test equipment. I think removing the balun should not affect the performance of the part and you can directly input the sensor. You should just take not if the impedance is matched with the sensor. Thank you.
