Part Number: TLV2471 Other Parts Discussed in Thread: OPA310 Hi expert,
My customer is using TLV2471 as a voltage buffer with input from a voltage divider.
The voltage buffer will then connect to MCU ADC channel.
My customer is asking if a feedback resistor…
Part Number: TLV2471 Other Parts Discussed in Thread: LM7705 Hi everyone,
I have followed the schematic as below but there seems to be no value in the desired output.
Thanks to anyone who can help.

Part Number: TLV2471
Hello, I would like to ask some questions about TLV2471, I want to measure the high voltage V2(range is 5-50VDC),so I used a resistor divider to lower the voltage V2,then connect it to a voltage follower(TLV2471 used), the simulation…
Part Number: TLV2471 Other Parts Discussed in Thread: LMH6622 Hi Team,
Our customer is designing a Wien-bridge sine wave oscillator and is looking for a suitable op-amp with the following parameters: • F0 = 3Mhz • Vin = ±5Vdc • Vo = 1Vp…
Part Number: TLV2471 Hi Team,
Customer is getting the expected output when TLV2471 used in summing circuit. Below is the details.

I have re-tested the device configuration and am getting a good response based on "measured" inputs. The inputs (V1…
Part Number: TLV2471 For the TI paper "Sine Wave Oscillator" Application Report, SLOA060 March 2001 page 14, 8.1 WEIN Bridge Oscillators, Figure 12: He has the negative input of the op amp grounded. He also says that the Vref 2.5 V plus connection…

Hi Ismail,
I'm not sure what you are doing. But usually a Wien bridge oscillator needs an amplitude stabilization (AGC automatic gain control) like shown in these threads:

Hi Danilo,
these are very typical simulation artefacts due to an unsuited time grid during the transient analysis. Even TINA-TI is showing them from time to time:

Keep in mind that the most TI's OPAmp SPICE models are optimized for…
The data sheet does not specify what the maximum undershoot could be on an input into the op amp. Our application uses a voltage follower (output tied to the negative input). We clamp the positive input with a diode to the negative power supply and a…
