Hello Delun,
I apologize for the long delay on a solution.
It depends what you are looking for in terms of your output current. It could be any of those inputs, it depends on your required switching time and power. In general, what you need the output…
Part Number: OPA690 Hi team,
My customer faced a leakage issue in the case of OPA690IDBVR:
Currently, my customer encountered a situation where the DIS_N pin leaks electricity to the VS+ pin.
Is this an official phenomenon of TI: OPA690IDBVR?
Test method…
Part Number: OPA690 Other Parts Discussed in Thread: TMS3705 , Hello Team,
We have a requirement that base on the TMS3705 circuit,
we need to add a filtered circuit to filter out waveforms below 110Khz and above 139Khz.PN:OPA690IDBVT
Do you have any reference…
Part Number: OPA690 Other Parts Discussed in Thread: OPA695 , Hi team,
this is our customer schematic diagram. U15 is a analog switch.
This is waveform, the above waveform is output, the below waveform is input.(R54-200ohm, R60-39.2ohm, R53-22ohm)
Then customer…
Part Number: OPA690 Hi Team,
The data sheet says the output is high impedance when its disabled but in simulation is appears to have a low resistance load. Feeding a 1V DC source back to the output of the amp through 25 ohms it appears the amp output…
Part Number: OPA690 Hello
I was looking for OPA690IDBVT but can't find it anywhere. I have PCBs. Now I am looking for similar replacement to make: (1) inverting amplifier with gain =1, (2) non inverting amplifier with gain 2 and (3) a inverting summing…
Part Number: OPA690 Can I power this OPAMP with +10V and -1V? , trying to use it to drive a load cell circuit and trying to avoid the cross over distortion by adding a small negative bias.
Part Number: OPA690 Other Parts Discussed in Thread: DAC2904 , , TINA-TI , THS3217 , THS3215 Hi team,
There is a question about DAC2904 output current to voltage conversion circuit. The customer is using OPA690 to implement this conversion.
The circuit is…
Part Number: OPA690 Hi all,
I need your help to understand how to reach the THD performances reported in OPA690 datasheet. Below the application circuit:
The input signal is 1Vpp, sinewave, 1kHz; the spectrum analyser input impedance is 50ohm. I get…
Part Number: OPA690 Other Parts Discussed in Thread: OPA3690 Team,
Can you please to identify if we have some possible better alternatives to OPA690 for the below use case? Voltage feedback OP-Amp for: Freq. range 0Hz…30MHz Input: Differential input…
