Manufacturer:Winbond Description: The transmitter and receiver channels consist of three amplifying stages each, F1,F2,F3 and F4,F5,F6.The inputs of the amplifiers must be ac. coupled because they are dc. vise at the internal reference voltage(2V) level. F1 and F4 are fixed gain amplifiers of 30,5 dB and 15.5 dB respectively, while the rest of them are of controlled gain type. The gain of F2,F3 as well as F5 and F6 is controlled by comparators. The comparator receives its information partly from the summing point of the transmitter, receiver and background noise detectors at CMP input and partly through the control input, CTR, which controls the gain dynamics (25 or 50 dB). Amplifiers F2 and F3 have the maximum gain when the transmitter channel is fully open, consequently the amplifiers F5 and F6 will have minimum gain and vice versa. See figure.1 and figure. 9. The positive input on transmitter and the negative input on receiver channel has a rather high input impedance. It renders a good gain precision and noise performance when used with low signal source impedance. The differential input of the transmitter channel can be used to suppress unwanted signals in the microphone supply, see figure. 5. |
