Hello guys,

I had made a differential circuit for measuring ac voltage and current. In simulation the entire circuit is working and i am getting desired gain(6.8k/2.068M) for u1 ,gain(5k/1k) for u2. But in practical…

Hello,

I am currently developing a circuit for solar cell voltage measurement. I'm using a 100 mΩ shunt resistor which connected to cell parallel. I am planing to measure voltage with a ADC. For measuring with ADC a…

I'm using the OPA387 as an integrator.  It's part of a servo loop controlling the DC output of another amplifier. The power rails…

Dear e2e support,

My customer is looking for the lowest noise possible AOP solutions at low frequency.

Choppers technologies such as the OPAx387 seems to be the best approach.

Question is: when we cascade several choppers, can it…

Hello,

I am using OPA387DBVR for my current sense design and there is a lot of noise on the input and output side. I saw there is a internal low pass filter but its frequency is too high. I need…

Hello TI experts,

My customer want to use OP amp with K-type thermocouple, to measure the temperature of the device.

actually they used thermocouple to digital converters before, but now they…

Tying to fine-tune a simple amplifier based on on OPA387 I found out that the higher Riso resistor value the lower the stability - see the diagram below, phase-margin(Aol)=61.5°@Riso=100Ω.
When Riso is 51Ω, phase-margin (Aol…

Hello,

I would like to order a few pieces of POPA387DBVR.  The website shows that stock is available, but will not allow me to add them to my cart.

I tried asking customer support (online chat), and they were, unfortunately, completely…
