Hi, I am using LT6230-10 for sensing the voltage across a sense resistor with a gain of 10, but when I simulate it does not work when -Ve supply of the opamp is grounded. Below is my circuit. Please suggest.
It's working only when -Ve supply of the opamp is connected to a -ve voltage. I mean I want to use this opam in a single supply only. I do not have -ve supply on my board. Please suggest why this opamp does not work or output saturates when using single supply
The data sheet says the input voltage range is 1.5V to 4V when running on +5V and ground.
thanks for the reply.
so that means I need to have at least 1.5V at R1 (ie opamp input) when running on +V and ground.
Currently, I have 100mV on R1(opamp input) which is out of input voltage spec. For 100mV input I need to supply +5V and -5V for which input voltage range is -3V to 4V
is my understanding correct?
