Unbalanced Mic: G = 5.1 (+14.2dB)
G = 0 to 22.8 (+27.2dB)
'4580 output voltage swing and common mode input range is to within 3V of rail worst-case, within 1.5V typical
Balanced Mic: G = 5.1 + 5.1 (+20.2dB)
Total Gain = +41.4dB (unbalanced)
+47.4dB (balanced)
Fc=35kHz to inf
Fc = 80kHz
Design for:
Fc = 28Hz
