Absolute Maximum Ratings*
*
Note 1: Refer to Figure 3 & 6 for appropriate biasing values
Note 2: Tip and Ring drivers to be limited to about 50mA externally (Figure 5). If the UD pin is asserted for longer than 5 seconds, then
PD should be asserted to power down the device. The device should then be checked (by de-asserting PD) every 5 seconds.
Recommended Operating Conditions
‡ Typical Figures are at 25°C with nominal supply voltages and are for design aid only
Note 3: For a 1.2Vrms 20Hz input at RV terminal (Figure 4) and with RC pin set to +5V.
Note 4: Refer to Figure 3 & 6 for biasing values
14
Exceeding these values may cause permanent damage. Functional operation under these conditions is not implied.
