Part Number: OPA837 Other Parts Discussed in Thread: OPA832 Hi community,
I hope everyone is safe at the current time.
Actually, I was trying to design a buffer and LPF circuit with a single-supply design using OPA837 op-amp and I tried to follow Figure…
Part Number: OPA837 Other Parts Discussed in Thread: OPA838 , OPA2837
I was going to use this table in an article discussing max linear output current - might be a few errors here, this is in the 5V table,
1. Perhaps the overtemp output voltage swings…
Part Number: OPA837 Other Parts Discussed in Thread: OPA810 Hi,
I have a rather general query regarding offset voltage and bias/offset current specifications, given in datasheets. But for reference I've mentioned OPA837.
I was doing some error analysis…
Part Number: OPA837 Hello,
Are the input bias currents modeled in the OPA837 spice model? According to the notes in the model, the bias currents should be modeled.
However, the simulation shows bias currents of ~17uA. According to the datasheet the bias…
Other Parts Discussed in Thread: OPA837 Hi engineers, for deepen understanding of op amp parameters, I want to build different test circuits for various op amp parameters, but the datasheet just introduce some test condition, so I need some document which…
Hello Michael,
regarding the load: It is a reference voltage for a sensor. When board 1 (with op amp 1) fails, board 2 (with op amp 2) shall provide the reference voltage. So your assumption on paralleling two op amps is correct.
Thanks for the link to…
Hi Mike,
Thank you for quick reply. OPA837 input range is +-1V, so I will have to rescale my input. But its good that it allows multiplexing. Thank you for help.

Hi Pedaiah,
+/-3.3V supplies and 0.5V output common mode is fine, the resistor values were chosen to give a gain of -0.4 (G= -Rf/Rg) to take your 2.5V signal down to 1V.
I will attach the following simulation using the new rails and Vocm:
