Rja=111.3, Tj= 150 150=25+111.3*Pd. maximum Pd = 1.12W. so the this device maximum power loss is 1.12W, is that correct? or you have any comments?

In my application, I have estimated my TIA OPA320 circuit output noise= 480uV. It is a lagre value. I want to use RC low pass filter to reduce the noise. 1. I want to confirm the Noise Bandwidth when I use RC low pass filter on OPA320 output pin. The new Noise Bandwidth=1.57*1/(2*3.14*RC)? 2. If the 1st step is correct, I can use the new Noise Bandwidth to recalculate the OPA320 Output noise? I can use the new Noise Bandwidth instead of the formula Noise Bandwidth for PPT page41- page44? Then get a new output noise. 3. In my application, I need to use the TIA output value to as the input signal to design a G=100 phase amplification. If TIA OPA320 output total noise=100uVrms, How to calculate the output noise for only TIA as the input voltage? https://e2e.ti.com/support/amplifiers-group/amplifiers/f/amplifiers-forum/1042188/opa656-peak-detector-2mhz-does-not-function/3856231#3856231Thu, 07 Oct 2021 12:54:00 GMTcb01d8b2-d089-468d-babb-77d1d8683490:40bd9375-49d6-463d-bb5a-75adc4ce2b1cMichael Steffes You are not inserting the TINA files so hard to know which model rev you are using, You should check the DC input bias current for the two models into the V+ node. Oddly, I went into the OPA656 web folder - not TINA model there anymore - there are of course models around but not sure where you got yours? https://e2e.ti.com/support/amplifiers-group/amplifiers/f/amplifiers-forum/1042213/opa388-about-the-conditions-of-high-temperature-and-high-humidity-test-thb/3856212#3856212Thu, 07 Oct 2021 12:29:00 GMTcb01d8b2-d089-468d-babb-77d1d8683490:b6b20c7a-8c10-4389-91e7-c1407b1607e3Kengo.Y How much input voltage is the V+/V-?

Gain=2, That is 212nV*2=424nV, 369nV*2=738nV.

FM radio frequency is 75~108Mhz. 1. Is TRF37A75 suitable as an FM radio frequency amplifier? 2. Does TI have a dedicated RF AMP for FM frequencies? 3. Are there L,R,C values suitable for 75Mhz ~ 108Mhz amplification? (Based on TRF37A75 basic circuit) Thanks! Downey Kim.

Requesting you to please review above circuit, by putting two no series diodes(1N914) in +ve supply part to reduce the +ve supply by 1.4V i.e, net supply voltages are +13.6 and -15V, which resolves my problem. Let me know any technical issue/ Reliability issues with above concept.
