Part Number: OPA810 Tool/software: Hi TI expert team
Is ther any OPA810 spice model that I can imprt to simulation tools for system simulation? Although there is the tina model on line but I need to use another simulation model taht can import spice…
Part Number: OPA810 Other Parts Discussed in Thread: TINA-TI Tool/software: I got your feedback on to implement negative capacitance using OP AMp. However, the biggest problem is on stability of your suggestion circuit. I would like to get CFOA circuit…
Part Number: OPA810 Other Parts Discussed in Thread: THS3491 Tool/software: 1. how to use a operational amplifier to create a negative capacitance values with frequency response with 20Mhz
Part Number: OPA810 Tool/software: Hi,
in my simulations the output of the OPA810 unfortunately goes far below the negative supply rail (0V). I think there is an issue with the spice-model. In my example please see the "comp_out_down"-signal, it goes…
Part Number: OPA810 Other Parts Discussed in Thread: LM358 Tool/software: Hi,
I'm deep diving in op-amps. I noticed there is a difference in 'Open-Loop Gain and Phase vs Frequency' between LM358 and OPA810. And I noticed that there is only one phase…
Hello Aditya,
Your answer discussed possible workarounds. (By the way, pull-up to Zener is not a good idea as it will degrade line regulation.)
Your reply does not answer the main question -- why on earth the op-amp with SUPPOSEDLY 2pA input current…
Part Number: OPA810 Other Parts Discussed in Thread: OPA2197
I bought OPA810 from Digikey. I ran into such a problem while doing the tests. When I compared the input and output in the voltage follower circuit, I observed that there was distortion…

Part Number: OPA810
Here is my OPA810 applicaiton circuit. There are 4 same circuit shares the same M5VA ( -5.0V) power supply.
But it cause the overload power supply, the power supply capability is -80mA.
From OPA810 datasheet, it's max 5mA for…
Part Number: OPA810 Other Parts Discussed in Thread: OPA2863A , OPA863 , OPA828 Hi Team,
We have a problem with too high quiescent current of opa810.
According to the datasheet, the current consumption of a single amplifier should be approximately…
