Philips TCA980
The TCA980 is a monolithic integrated microphone amplifier. 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.| Part No. | TCA980 |
