Datasheet Summary
II II TAA970
MICROPHONE AMPLIFIER
- The TAA970 is a monolithic integrated microphone amplifier for use in telephone systems.
It is patible with both piezo-electric and dynamic microphones of suitable impedance and sensitivity, Special 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
