Part Number: LMV841 Other Parts Discussed in Thread: LMV844 , OPA2171 , , LMV842 , TINA-TI , OPA4171 For OPA2171 you don't only provide a figure for max allowed C_LOAD and recommend R_ISO, you also provide a graph of R_ISO vs C_LOAD for phase margins of 45…
Hello Anbu,
Some questions so I can try and help debug:
1. I am assuming that "LMH6158 -IN" is in fact 2.5V.
What is the voltage at R1, R3 junction (lower LMV842 output pin)? It should be around -2.5V (assuming you have not applied any "Offset…
Other Parts Discussed in Thread: OPA656 , LMH6518 , LMV842 Hi Hooman,
Is it possible to replace the JFET LNA of figure 69 of the datasheet with some monolithic IC like OPA656? I want to keep all the properties of the JFET LNA. Please advise.
Regards,

Paul,
Not shown in the sketch, but the 10V is provided by an REF5010 part. My error concern is with an open circuit for the resistor divider, 10V through the 1MEG, 100K and into the +IN pin I do not get 10V out of the LMV842. I get about 8.9V. As I add…
