Dear all
I find the Vos vs. Vcom curve as below:
We use TLV9062 as constant current source, which is very sensitive to the offset voltage leap. In order to simulate the offset leap, I use a voltage source doing parameter simulation. According to the results, if there is around 1mV leap on Vos, the output voltage will change around 58mV. But when we test on board, find there is no such leap at the output. So I want to know whether the TLV9062 has offset trimming circuit internally or not.
Tks and Regards.
