Here the schematic diagram of mic preamplifier which build based on operational amplifier TC251. The TLC251 is operating in low bias. The circuit works with only 1.5 V supply draws electric current of only 10 mA, so the battery operation will be prefered.Circuit frequency response is 3dB, 27 Hz to 4. 8 kHz. Frequency Response:
