data sheet as2522b austria micro systems revision 3.4 page 5 of 19 functional description dc conditions the normal operating mode is from 15ma to 100ma. an operating mode with reduced performance is from 5ma to 15ma. in the line hold range from 0ma to 5ma the device is in a power down mode. the dc characteristic is determined by the voltage at li- pin and a 30 ? resistor between li- and ls-pin. it can be calculated by the following equation: v ls = v li + i line * 30? . v li can be programmed to be 3.5v or 4.5v. 2/4 wire conversion as2522 has a built-in dual wheatstone bridge with one common ground. this provides a maximum of independence of ac-impedance and side tone from each other. one can adapt side tone without changing the ac- impedance. ac-impedance the ac-impedance of as2522 is set to t.m. 1000 ? . with the external capacitor at ci-pin it can be programmed complex. with an external resistor of approx. 1.5k ? connected to the ls-pin it can be programmed to 600 ? . side tone a good side tone cancellation can be achieved by using the following equation: z bal /z line = 10 transmit path the gain of the m1/m2 ls is set to +37db. this gain can be changed by programming from +30db to +45db in 1db steps (register txgain ). the input is differential with an impedance of 10k ? . the soft clip circuit limits the output voltage at ls to 2v p. there is llc for this path. the gain of the m3/m4 ls is set to +46db. this gain can be changed by programming from +39db to +54db in 1db steps. the input is differential with an impedance of 10k ? . the soft clip circuit limits the output voltage at ls to 2v p . there is no llc for this path. receive path the gain of the ls ro receive path is set to +1db. this gain can be changed by programming from -6db to +9db in 1db steps (register rxgain ). the receive input is the differential signal of ri and stb. the soft clip circuit limits the output voltage at ro to 1v p. it prevents harsh distortion and acoustic shock. there is llc for this path. the gain of the ls lo1/lo2 receive path is set to +29db. this gain can be changed by programming from +22db to -37db in 1db steps. the user can also change the gain via register vol (see section "handsfree"). the receive input is the differential signal of ri and stb. the soft clip circuit limits the output voltage at lo1 of lo2 to 1v p. it prevents harsh distortion and acoustic shock. there is optional llc for this path. line loss compensation the line loss compensation is programmable (register 0x0c ). when it is activated, the transmit and receive gains for both i/o?s are decreased by 6db at line currents from 20ma to 50ma or from 45ma to 75ma. handsfree the handsfree function allows voice communication without using the handset (full 2-way speaker phone). two voice controlled attenuators prevent acoustic coupling between the loudspeaker and the microphone. the voice switching circuit has three states, namely idle, transmit or receive. in receive mode the attenuation of the receive path and the transmit path can be controlled by register vol between 0db and -20db. the following table shows how voice switching is controlled ams ag technical content still valid
