The KA8503 is a telephone low voltage speech network which includes mic amp. transmit amp, side-tone amp, receive amp. It handles the voice signal performing the 2/4 wire interface and changing the gain on both sending and receiving amplifiers to compensate for line attenuation by sensing the line length through the line current. Application dependent parameters such as amplitude of each amp, sidetone level line balance, and frequency response are controlled by external components. Each gain can be controlled by external component exchange. The receiver output driving capability is adjustable.
1. Adjust Sending and Receiving Attenuation Length
2. Mute Function
3. Side Tone Balance Network Constitution
4. Low Voltage Operating
5. AC Impedance Matching
6. Uses in Inexpensive Components (5 Capacitors & 10 Resistors)
7. Uses a minimum of external components
