While this is being done, the auxiliary amplifier continues to stabilize the mean dc level at the DUT output. Figure 5. AC gain measurement.
Web8 jun. 2024 · Current Sense Amplifiers are special-purpose amplifiers that output a voltage that is proportional to the current flowing in the power rail. Current sense amplifiers are also called current shunt amplifiers because it uses a shunt resistor in the power rail that provides a small voltage drop when current flows through the resistor. This voltage … Web3 dec. 2024 · Specifically, you’ll need a 1kHz test tone recorded at 0dB - and a source at which to play it into the preamp. Output should be monitored with a distortion detector (like an SMD DD-1) and output voltage measures with a true RMS volt DMM. The amp is a tad more complex ...
