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 Other Parts Discussed in Thread: TIDA-00854 Tool/software: WEBENCH® Design Tools I have some questions about TIDA-00854 Micropower Electrochemical Gas Sensor Amplifier Reference Design
In the schematic design document of TIDA-00854…

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…
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.
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 is…

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)
- reduced…
Other Parts Discussed in Thread: LPV802 , TINA-TI I am trying to use LPV802 chip for a Schmitt trigger. I mainly use ADS to design a circuit, so I tried to import LPV802 PSPICE model (.lib) file in ADS, but it cause me syntax error during acting running…
Hi Matthew..
Thanks for your reply.
Surely your answers had cleared most of my doubts..
About RF, I wanted the output of the sensor to be 0-5V and spec sensor's sensitivity factor is 8nA/ppm and max range is 20ppm. So I calculated the RF according to…
Hi Nick,
I would do the phase stability analysis by including the JFET circuit of the PIR sensor and its output impdance and by including the input capacitances of the following comparators:

As you can see I get the same result as David…
