I plan on using this electret
I plan on using a schematic similar to this except I was planning on using a 1.5 volt Type N battery.
The input impedance of the amplifier circuit is roughly 600 ohms.
I read somewhere that changing the pull up resistor value changes the gain of the circuit. Is this true?
If the gain is a fixed value I have plans to build an appropriate attenuator pad to reduce output to 35 millivolts but I would prefer not to do this if possible.
I was wondering if anyone would be able to help me calculate values of resistors to achieve the desired output level of 35 millivolts into a 600 ohm load powered by a 1.5 volt battery...
Thanks in advance...
