Electret Mic Gain at Bradley Guidry blog

Electret Mic Gain. Can anyone tell me what is the default gain of electret microphone amplifier 4466. Maybe you're fine as is if you will be using a high enough resolution a/d so that the signal can only use part of the range. The resulting product, lmv1012 has about an 18db gain increase over the same ecm with a jfet inside. Output swing levels at the maximum. 12nv/rthz is still noisy but probably what you could expect for such a low power device. I need the gain, to calculate the db spl value. With this gain, you need 50 mvpp from the mic, which sounds a bit high. The noise falls to about 12nv/rthz at a gain of 200 (rgain = 1.1k between pins 1 and 14). In this project guide, we show you how to use your desktop pcb milling machine to make an electret mic preamp.
