Secondly, you're better off measuring current and converting that to a voltage. You can use a shunt resistor and feed that into an op-amp, or use an IC like a Hall sensor. There's lots of options for current sensing, use whatever fits your needs. Logged ...
Using the transistors shown, the configuration can supply over 1 amp. However, unlike the use of additional OPA454 op-amps, the complementary transistor pair may not provide the level of distortion-free performance and linearity needed. If this higher current is needed and transistors are the pre...
