MUTE STAND-BY FUNCTION. The pin 5 (MUTE/STAND-BY) controls the amplifier status by two different thresholds, referred to +VS. When Vpin5 higher than = +VS -2.5V the amplifier is in Stand-by mode and the final stage generators are off. When Vpin5 between +VS -2.5V and +VS -6V the final stage current Sep 9, 2015 Features. 80 W + 80 W output power at THD = 10% with RL = 6 and VCC = 32 V. 70 W + 70 W output power at THD = 10% with RL = 8 and VCC = 34 V. Wide-range single-supply operation. (14 - 36 V). . High efficiency ( = 90%). Four selectable, fixed gain settings of nominally 25.6 dB, 31.6 dB, input class-D amplifier with integrated closed-loop. Provides: feedback technology (known as PurePath HD. Signal Bandwidth up to 80 kHz for High- technology) with the ability to drive up to 300 W (1). Frequency Content From HD Sources stereo into 4- to 8- speakers from a single 50-V supply. Ultralow 0.03% THD GENERAL DESCRIPTION. The AD73761 is one of the few high voltage, high performance digital potentiometers2 on the market. This device can be used as a programmable resistor or resistor divider. The AD7376 performs the same electronic adjustment function as mechanical potentiometers, variable resistors, and Jun 16, 2005 The TDA8947J contains a unique protection circuit that is solely based on multiple temperature measurements inside the chip. This gives maximum output power for all supply voltages and load conditions with no unnecessary audio holes. Almost any supply voltage and load impedance combination can
