Good morning,
I used OPA552on my card with the following characteristics:
Vcc 9 to 25Vdc
Gain x10, non-inverting
Vin 0.5Vdc with Vout 5Vdc or Vin 1.25Vdc with Vout 12.5V or Vin 2Vdc with Vout 20Vdc
Iout 200mA
The VCC changes along with the selection of the VIN.
I had no problems but rechecking the data sheet I understand the minimum Vin = V- + 2.5V .
If so should be the input is not polarized is then VOUT wrong .
What I did not understand?
