Audio Power Amplifier 6.1 Electrical Specifications VBAT = 3.6V, T A = 25°C unless otherwise noted. High power mode, 100 nF capacitor connected between CBP and GND Audio, 470 nF input capacitors, load = 8 Ohms. Table 4-1. Absolute Maximum Ratings* Operating Temperature (Industrial)...............-40 ° C to +85° C *NOTICE: Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or other conditions beyond those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reli- ability.
