Other Parts Discussed in Thread: OPA209 , TINA-TI OPA209 Gain band width per data sheet is 18 MHz. However, when I simulate it in a non-inverting amplifier for a gain of ~ 200, I get a 3 dB bandwidth of ~ 1 MHz.
This doesn't make sense. (If the gain is…
Part Number: OPA145 Other Parts Discussed in Thread: OPA140 , OPA189 , OPA209 OPA145 is marketed as 20 V/µs slew rate. Figure 6-37 of the datasheet shows slew-rate induced distortion already at ~25 kHz for a 30 V supply.
I am wondering if this is…
Hi Red,
All of Kai's points regarding the circuit's response time are spot on and should be followed. And indeed, I would recommend splitting the high gain up evenly among two amplifier stages.
It is interesting that the design sets a high gain…
Hi Glenn,
Sorry you ran into a problem with our OPA209 simulation model. The first model that you mention is an older, but well vetted OPA209/OPA2209 simulation model that was released sometime in the 2010 timeframe. It has been included in the TINA-TI…
Part Number: ADS8568 Other Parts Discussed in Thread: ADS8688A , OPA209 Hey everyone!
I've looked at the ads8568 briefly in the past but now need to implement it in a design.
Concerning the output data format in serial mode. If I have this correctly…
Part Number: OPA4209 Other Parts Discussed in Thread: OPA209 , OPA2209 , Hi, Is channel separation vs frequency plot available for quad version? It is not in a datasheet unfortunately. Or at the bare minimum, data at 1Khz or 10Khz please? Cheers,
Alex
Part Number: OPA2192 Other Parts Discussed in Thread: OPA209 , OPA211 , INA188 , INA828 Hi,
Our customer wants to use OPA2192 to measure high current. The maximum current is 200A. But the noise is very high and can NOT recognize the normal signal.
Please…
