  • Preamplifier AD797AN for Wireless Noise Monitoring application

    I was designing a microphone pre-amplifier circuit for Wireless Noise Monitoring application.

    I used an amplifier AD797AN (datasheet:http://www.kynix.com/uploadfiles/pdf/AD797AN.pdf ) which connected to a 9V power supply. The multisim simulation of the circuit with a function generator gives the expected gain of around 7.8. But the same circuit in the breadboard with the microphone gives the gain of only around 5. Please let me know what improvements are needed in the circuit to get the expected gain of 7.8?
