Low noise preamplifier circuit
Shown is a typical low-noise preamplifier circuit , which can be used in audio circuits as an amplifier for microphone signals
and head signals.
In this circuit, the signal is sent from the input end, filtered by the capacitor cl coupling and the filter circuit , and then sent to the low-noise preamplifier HA12Q17 I;FJ@, ⑦
pin. Output the amplified signal .
