The TA3021-60 is a 250W (4), two-channel Amplifier Driver IC which uses Tripath's proprietary Digital Power ProcessingTM technology. The TA3021-60 has four breakthrough features not found in linear amplifier solutions: 1) ability to control and monitor the amplifier by a two-wire digital serial bus that is compatible with Philips' I2CTM bus, 2) a volume control which dramatically reduces total system noise, 3) optional differential inputs and 4) a mute on silence feature which automatically mutes the amplifier when no input signal is present. Class-T amplifiers offer both the audio fidelity of Class-AB and the power efficiency of Class-D amplifiers.
