Tool/software:
Hello TI Team,
I am using TLV9062 in two configurations.
1) Buffer: Unity gain buffer with 1.65V offset
2) Diff Op-amp: Gain of 5 with 1.65V offset
Differential input voltage to circuit: 3mV to 400mV signal with 20KHz frequency.
This circuit amplifies voltage across MOSFET (Turn On state), in case of OFF state of MOSFET, input voltage increases upto 24V. Op-amp input terminal is clamped to 3.3V. So, every 50us op-amp output goes into saturation. As per datasheet it should come out of saturation mode within 200ns.
There is a different behavior of op-amp related output for two configurations.
In case of buffer, output settled within 2us and follows signal.
But in the case of amplifier (with gain 5) after settling time output does not follow input, it gradually reduces. Is it something related to slew rate of op-amp? Is there any relation between op-amp closed loop gain and slew rate? I have attached a waveform for your reference.
