Part Number: OPA4314 Other Parts Discussed in Thread: TLV4333 Tool/software: Hi, so I'm designing an amplifier/buffer to measure bio-signal (EEG) and need 1. high input impedance (>100M) 2. ultra low noise (<<10uVpp @ 0.1-10Hz) 3. low cost 4. low power…
Part Number: OPA4314 Other Parts Discussed in Thread: OPA4310 , OPA4991 , OPA2837 Hello, do we have an any data of the offset matching of the 4 OpAmps?
Regards, Holger
Hello Daniel,
Thank you for the feedback ?
Is there any model for ltspice of the OPA4314 ?
i found the tina-spice model but I'm unable to implement the circuit I want there.
Thank you.

why is the input voltage noise (f=0.1Hz to 10Hz) specified with 5µVpp while the oscillogram shows only about 1.5µVpp…
Part Number: OPA4314 Other Parts Discussed in Thread: OPA2990 Hello, My customer has some questions for Figure 5. Offset Voltage Production Distribution in the datasheet(SBOS563G).
Q1
This graph shows data in a range of +-1.4mV while max offset…
Part Number: OPA4314 Other Parts Discussed in Thread: TINA-TI Hello,
For our application, we must design a simple filtering circuit consisting of a 50/60Hz notch filter to remove ground noise, followed by a 10KHz low pass filter.
The design parameters…
Part Number: OPA4314 Hi team,
There is the following description in the data sheet though, Is it okay to apply more than 0.5V at input pins under no supply condition if the current to the input pin is 10 mA or less?
My customer plan to use following…
Hi Andrew,
I have been out of the office on vacation a couple of weeks. Thank you for all the updates on your OPA4314 application and resolution of the stability issue. It is great that you were able to find a solution. There is always much more to…
Dear Ron,
refer to ADC read value, the noise is about 50uV @OPA is TLV9054.
But I hope the read value varied < 20uV.
the ADC has the digital filter and PGA inside. I set PGA gain=8 for measuring 100mV.
As I tested 4 kind of OPA, I found that…
Other Parts Discussed in Thread: TPS61041 , OPA4314 , TPS61040 Hi,
I'm working with the TPS61041 and TPS7A4901 to power an audio amp. The TPS61041 steps up a single cell lithium battery to around 5.85V and the TPS7A4901 regulates and cleans this down…
