Part Number: OPA387 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…
Part Number: OPA387 Other Parts Discussed in Thread: TINA-TI 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…
Part Number: OPA387 Other Parts Discussed in Thread: TLV333 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…
Part Number: OPA387
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 51 Ω, phase-margin (Aol…
Part Number: OPA387 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…
Part Number: ADS1114 Other Parts Discussed in Thread: OPA387 , I have an ADS1114 receiving an input signal between 0V - 4V, the signal goes through an OPA387 set up as a buffer, just before the A0 input of the ADC i have a low pass filter for 80hz made…
Hi Stefan,
Both OPA387 (5 MHz) and OPA388 (10 MHz) are MUX-friendly, they both use a similar switching architecture at the front end as OPA189. For lowest noise, OPA388 is the best choice, but for lower power, OPA387 is the best.
Let me know if there…
Part Number: OPA182 Other Parts Discussed in Thread: OPA387 , OPA187 , OPA186 Hello, My application requires lowest possible offset drift with + / - 5V Dual Supply. I am checking OPA182 in my design but I see the common mode voltage range is (V–) – 0.1…
Hi Naga,
As Mike implies, you need to provide us some design and accuracy requirements. I do not know what performance specification you are looking for.
As an example, here is a circuit. It is not perfect, but it may be close enough in terms of accuracy…
