Part Number: OPA992-Q1 Here is my TIA circuit
Since this circuit has high feedback resistor (100Meg) for OP-AMP,
Vo would be about 300mV when power off due to environment light,
and Vo would be about 100 mV when power on due to 0.1 bias of V+,
since I do not know your circuit, there's no simple answer. Keep in mind though, that the ADS7961 only withstands a maximum negative input voltage of -0.3V. So, a negative supply voltage for the OPA2810 and OPA992 of way more than -0.232V (LM7705…
Part Number: OPA992 What if using +35V and -5V for OPA992 power supply?Will it case unstable or damage?
Because my signal DC component only touch -3V buy need too up to+30V
Any think i need to check when using Non-symmetry supply rail?
Yes the OPA992 would work, I was hesitant to promote it at first because this also has slew boost, however Figure 6-15 shows that with an input step of 0.9, the expected slew rate is 22 V/us.
The other thing to consider when implementing…
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…
don't forget the maximum negative input voltage range of ADS7961:
Part Number: OPA1688 Other Parts Discussed in Thread: OPA992 , TINA-TI Hi,
I developed a current-generator stage using the OPA1688 device. The goal is to generate a current proportional to a analog voltage I can control. The current is driven to a 60-Ohm…
Other Parts Discussed in Thread: OPA992 Hi there,
I have a question about the Ti Filter Design Tool.
I've designed a CCT using MFB topology with a cut-off frequency of 80KHz.
However, when I try calculating the cut-off frequency I seem to get 102…
