I need to amplify the output range of a DAC chip from (0-3.3 V) to (0-10 V). Unfortunately, I cannot simply use an inverting OpAmp circuit, because the output needs to stay positive with respect to digital GND.
Is it possible to use an NPN transistor in the feedback circuit, in order to achieve the amplification factor of 3? I ran simulations with LTSpice, and below circuit gave me the expected results - R3 is supposed to lazily simulate the input impedance of the device to be controlled by 0 to 10 V. Frequency of the operation is below 1 kHz.
I am not an electronics engineer and am seeking for advice, for perhaps better alternatives.
