Part Number: OPA2355 Hello,
Can you please let us know the Life Cycle, Correct years of to-EOL of the below part of Texas Instruments as we are unable to find that data in Texas Instruments website.
"OPA2355DGSA/250" ,"Texas Instruments", "Op Amp…
Hi,
I do not generally use floating voltage sources, but instead use an ideal transformer to convert a single-ended signal to differential. Please see attached schematic. The center tap is used to level shift the dc input to the amplifier.

Other Parts Discussed in Thread: OPA2356 , OPA2355 , OPA355 , OPA356 , TINA-TI Hello, can anyone tell me the different betwen OPA2356 and the OPA2355?
I can only see that the OPA2356 have no enable.
It is importent, because I want to simulate my circuit…

Hi,
I have designed a TIA amplifier using OPA2355, the circuit works well, however there is one problem I need to address.
I get an input signal that is 1MHz, the transmitter turns on and off…
Other Parts Discussed in Thread: OPA355 I have built a 4 stage transimpedance amplifier, the first 2 stages are for gain and the last 2 for active filter.
My signal is 1MHz with duty cycle of 50%. The active filter blocks anything above 1.5MHz (LP…
Other Parts Discussed in Thread: OPA2356 , OPA2355 Hi All,
we are looking for ADA4891-2 replacement. Can you propose a TI par with similar characteristic?
Br,

Dear TI team,
I have a question for you about the contents described by Mr. kai.
① It is possible to calculate that the input impedance is 70 Gohm, but what is the variation (deviation) in the input impedance?
② There was the following description…
HEre are your choices Rocky, better work on improving the ADA4817-2 thermal issues - no direct replacement it seems. These are JFET or CMOS input descending Gmin SSBW. Many are not unity gain stable - the closest might be the OPA2355 and OPA2356 - they…
Hi John,
I have a gain of 420K in first stage and about 20 in the second stage. I use the same opamp (OPA2355) in the board. I have 15V, 4.5V, 1.8V available on the board.
I have a strict risetime requirement of 300nSec at a signal of 1MHz. I use…
