TAA970 - MICROPHONE AMPLIFIER

Key Features

  • are: - almost constant voltage gain and d. c. voltage drop with supply current variations of 10 to 100 rnA. I - output voltage before limiting: 1 V (r. m. s. value) - operation is independent of supply voltage polarity - gain can be set to either of two values - only one external capacitor required - output impedance determined by internal feed back Supply current QUICK.
