1. So Essentially what you are trying to say is that I need a VCVS at the output of the OPAMP and externally Bias it with a DC operating point like shown in the figure plot below when I have to simulate the AC characteristics of the OPAMP? Where Vmid…
Part Number: OPA323 Other Parts Discussed in Thread: TLV365 Tool/software: I’m using OPA323IDCKR as a voltage follower, powered by +/- 2.5V, input is sine wave of 2.3MHz 3.5V pk-pk, output is totally unloaded (only with 10x oscilloscope probe). As you…
Good question. The rule of thumb depends on the output quality expected.
Here is the OPA323 unity gain buffer sim. At 1/1000 the BW (20kHz), gain peaking (gain error) starts. This happens when open loop gain's phase drops below -90 degrees. The gain peak…
Part Number: TLV9151 Other Parts Discussed in Thread: TLV9161 , TLV9051 , OPA323 Tool/software: Hello,
I have a problem with the op amp TL9151SIDBVR. It operates in a differential to single ended circuit. The problem is that for frequencies above 50kHz…
Other Parts Discussed in Thread: OPA1633 , OPA323 , TAC5112 , PCMD3140 , PCMD3180 We are making a stethoscope using MEMs digital Mic with 20hz to 20Khz and wish to use TI Preamp and Op Amp and are thinking to use OPA323 as Preamp and OPA1633 as amplifier for…
Thanks for the answer. We can go with the software filters and are thinking of using OPA323 and TAC5211 combination.
Please suggest if it is okay of some other ICs are good?
Hey John,
Understood, in that case I recommend OPA992 be used for the first one and OPA323 be used for the second one. I think we currently have only released the OPA4323 but the single channel is likely to release in the next couple of months. If the…
