Part Number: OPA209 Other Parts Discussed in Thread: TINA-TI , , LMP7701 , TLC277 , TLC272 Tool/software: TINA-TI or Spice Models I build a schmitt trigger circuit to transform sine wave to square wave. But I couldn't achieve to remove offset from output of…
Part Number: OPA209 For Op Amps made of BJT, we are using an resistive circuit for input bias current cancellation. Which kind of method is used to cancel the input bias current for an Op Amp made of CMOS?
Kindly please answer....
Thanks in advance.…
Part Number: OPA209 Other Parts Discussed in Thread: TEST Hi Sirs,
Sorry to bother you.
OPA209 have some THD+N error
Description:
In the [QC Test Item_11] AI Dynamic test, when imputing the signal of 20KHz / 6.3Vrms(17.825Vpp), the THD shows that there…
Part Number: ADS1278 Other Parts Discussed in Thread: THS4541 , , OPA209 Hi experts,
My customer reported that frequently their ADS1278 input channels damaged. Customer design is: vibration sensor -> OPA209 (+/-12V power) -> THS4541 (+5V power) -> ADS1278…
Other Parts Discussed in Thread: LM7301 , OPA209 Hi,
I am using an OPA209 to build a 2.5V voltage reference. I use two 10kohm resistors to divide the 5V supply voltage and send it to the non-inverting input of an OPA209. The inverting input is shorted…
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…
