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

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…

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

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…
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 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…
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…
