Part Number: LPV802 I have the LPV80 used as a transimpedance amp, and have found that its power consumption increases significantly. When the photodiode is 'off' I am reading the correct power consumption, but when it is no longer dark I am reading up…
Part Number: LPV802 Dears,
When I using LPV802 as inverter amplifier, I found it is unstable. The TINA simulation is as following:
The input capacitor is about 3pF. I calculated the zero of 1/β, is equal to 1/(2*π*3pF*5k)=10MHz. I think this circuit…
Hello,
The text located in section 2.3.2 of the reference design explains that a "potentiostat bias feedback circuit" is used to "maintain the proper sensor RE to WE electrode bias."
From my understanding, this circuit would be different depending…

How to simulate the phase margin of transimpedance amplifier（ example U1A ） with TINA
Give me a simulation reference circuit . Thanks. ，Thanks.
Part Number: LPV802 We design electrochemical gas sensor circuit using LPV802 amplifier with reference to "Comparing EMI Performance of LPV802 with Other Devices in a Gas Sensor Application"，But
we failed to solve the problem of electromagnetic interferenceWalkie…
Part Number: LPV802 Electrochemical gas sensor using LPV802 amplifier is easy easily disturbed by electromagnetic interference or Walkie-talkie （10V/m, 80MHz~1GHz）. How to solve this problem?
Give me some advice，Thanks.
Jo,
The ADs2016 workspace for the LPV802 is attached.
Just so you know, in general, a model can give different results in different simulators.
I mention this because we do our model development in Pspice or TINA. If the model's behavior in ADS…

Hi,
I have built a PIR AFE circuit closely based on this reference design.
The differences are as follows:
- using LM358AMX/NOPB (dual amp in SOIC package…
Other Parts Discussed in Thread: TIDA-00854 , LPV802 Hi.
I was designing ozone gas sensor (using SPEC ozone sensor-20ppm) taking TIDA-00854 in reference. I am confused with the value of R2 and R5 which are 0 ohms. And about the RF.. can I use a large…
Part Number: TIDA-00489 Other Parts Discussed in Thread: LPV802 Hello.
I'm attempting to measure the phase margin of a TI reference design (TIDA-00489) using the method outlined in https://training.ti.com/ti-precision-labs-op-amps-stability-spice-simulation…
