Part Number: TIDA-060029 Other Parts Discussed in Thread: OPA2810 , THS4551 , OPA301 , OPA300 , ADS127L11 , TMUX1104 , BUF634A , TINA-TI Tool/software: Hi,
In the design, can we use OPA300/301 replace OPA2810? I notice the OPA 300/301 have a 60dB AOL at 100KHz…
Part Number: OPA301 Dear all,
I am trying to build a simple filtering stage for baseband signals. Therefor I use an Opa301. The Problem is that when I want to filter a sinusoidal signal with a DC offset of 2.1V and amplitude of 100mV something strange…
Part Number: OPA301 Hello. In the data sheet, there is 40uVpp, 0.1-1MHz. I tried to get this number from the Noise density graph, but failed. Attached my calculations, based on you “Lecture Manual”. Data from the data sheet: Input Voltage Noise…
Hi Rakesh,
The OPA301, as with many other comparable devices, has some built-in offset voltage incorporated into the TINA-TI model. That looks to be around -1.7mV in this case (the OPA301 offset voltage room temperature limit is +/-5mV, so this is within…
Part Number: ISO224 Other Parts Discussed in Thread: OPA301 ,
Hi Team,
I plan to buy a ISO224EVM borad for test, I have some questions need your help, thanks in advance.
1. If VDD1 is 5V, can analog input be 12V and higher than VDD1?
2. if VDD1 is generated…
Other Parts Discussed in Thread: OPA301 Hello,
Thanks for the help with my last post on using the correct TI part in my triangle wave circuit. I am moving onto designing the second block of the overall system. I am dealing with closing the control loop…
Hi Michael,
Thanks again for your comments. I went with the OPA301 in the end as I don't need the enable pin from the OPA300. The (simplified) revised schematic now looks like this. We'll see where the signals clip when the board is made.
Cheers…
Hi Mandar,
Another possibility for lower noise may be to use OPA301 (3nV/RtHz, 150MHz, RR out, input CM voltage range to ground, 5pA max input bias current, 5mV max offset!) assuming that you have a means to correct / adjust for the large offset? With…
Other Parts Discussed in Thread: OPA301 , OPA2301 Dear all,
I want to condition an analog signal to a differential adc channel.
I decide to use the bellow circuit ( from TI note )
Where do I should to place an anti aliasig filter?

Other Parts Discussed in Thread: OPA301 Hi I am trying to incorporate opa301 in a simulation. Downloaded the spice files from TI and converted them as the manual says says. However the simulation return the error massage: " INTERNAL ERROR -- Divide…
