II II TCA980 MICROPHONE AMPLIFIER The TCA980 is a monolithic integrated microphone amplifier. It is. primarily intended for use with low-impedance microphones in telephone systems. The output of the amplifier is 22 mV/~ar when used with a microphone haVing an impedance of 200 Q and a sensitivity of 100 !-IV /~r. A capsule assembly containing the TCA980, a low-impedance microphone and aQ, 22 ~ capacitor can directly replace a carbon microphone. The d. c. supply to the device may be of either polarity.
