TI中文支持网Part Number:OPA4348
Hi, I would like to ask what is the open loop output impedance of the OPA4348, I can't get this from the datasheet. In addition, I would like to know the calculation method or simulation(TINA TI, etc.) method of the closed-loop output impedance.
Amy Luo：
您好，
下面文档讲了怎样测量open loop output impedance 和 closed-loop output impedance
