Microphone amplifier

Application:

Used in audio and video recording systems. Amplifies the signal of the internal microphone and transmits it over long distance (up to 5 km.) using a cable. A coaxial, phone or UTP cable can be used.

Technical parameters:

• Power supply: 8 to 30 V DC
• Consumption: 6 mA
• Frequency range: 40 to 12 500 Hz
• Nonlinear distortion: < 0,1 %
• Output impedance: 600 Om
• Non-symmetrical output: 0,8 V p-p
• Symmetrical output: 1,6 Vp-p
• Protection from pre-modulation, short circuit of outputs and power reverse
