2020年7月2日 · Instead of the OPA333 being powered by a potential difference that "sits above" GND by 5.1V, it is a voltage that "hangs below" the 400V bus by 5.1V. Since the current sense …

Now, to create the 1.65V reference, i'm using a 3.3V source, a resistive voltage divider, and a Texas instrument's OPA333 as a voltage follower. However, to individually adjust every …

2023年4月9日 · I have this circuit: I am asked to show that the transfer functions of the circuit is: I know that for non-inverting op-amps: \$ Z_{in}=\infty \$ \$ Z_{out}=0 \$ \$ H ...

2017年7月17日 · Possibly what might be a good choice for low voltage supplies is the OPA333 but you have given very little to go on so it's at best a guess that might point you towards a …

2023年10月30日 · The OPA333 controls Q4 as a variable resistance so that the voltage at its non-inverting (+) input equals to that at its inverting (-) input. The voltage at the inverting input …

2016年9月2日 · I'm attempting to simulate a circuit that is intended to take a 5V/GND input and make split +/- 2.5V rails with a virtual ground. When I try to simulate, LTSpice complains about …

2023年10月18日 · I'm new to using OrCAD PSPICE 16.6 and need some help. I'm trying to design a charge amplifier for a piezo sensor before building the actual circuit.

2020年10月11日 · I am trying to find the transfer function H(s)= Vo(s)/R2(s) but i am struggling to get it. I am assuming an ideal op-amp. V+=V- and that no current flows through the pins op the …
