Abstract: One example includes an amplifier system. The system includes a precision amplifier portion comprising a first input stage configured to receive an input voltage and a first output stage configured to generate an output voltage at the first output stage based on the input voltage. The system also includes a slew amplifier portion arranged in parallel with the precision amplifier portion and comprising a second input stage that receives the input voltage and a second output stage. The slew amplifier portion can be activated in response to a detected slew condition associated with the input voltage to generate the output voltage based on the input voltage.
