Daycounter Calculators

Daycounter separates circuit configurations, component properties, filters, motors and power supplies. Its inverting op-amp calculator takes gain and a desired output bias point, with a chosen R1 setting the scale of the remaining resistors. V1 is the input, while V2 supplies an optional offset and should be zero when no offset is needed. The form labels voltages in V and R1 plus output resistors R2–R4 in kΩ. This is useful when translating a gain/bias requirement into nominal resistor values for that depicted circuit. The separate non-inverting route and other circuit models should be selected according to the configuration being designed.
