MT6905 Datasheet | Maxic Technology

features very low 0.1% THD+N, high 90d B S NR, and therefore offer high quality sound. MT6905 delivers up to 5W power into a 2Ω load with an efficiency up to 80% and 1.6W into a 8Ω load with an efficiency up to 92%. The MT6905 features a low-power consumption shutdown mode. The gain of the MT6905 is externally configurable which allows independent gain control from multiple sourc es by summing the signals. Output short circuit and thermal overload prot ection prevent the devic e from damage during fault conditions The high efficiency and a low s hutdown current make the MT6905 an ideal choice for both battery-powered speakers and portable devices. FEATURES - High output power 5W @ VDD=PVDD= 5.5 V, RL= 2Ω, THD+N = 10% - 2.5V~5.5V single supply operation - Filterless and ultra-low EMI, can work with FM tuner without extra Ferrit e-bead ponents - Less than 0.1% THD+N - Excellent Power up/down “P op sound” suppression - Low quiescent current and low-power shutdown current - Few external ponents to save the space and cost - Over current/Short circuit and over temperature protection - Available in SOP8 package (P b-free) MT6905 integrat es Maxic’s unique EMI suppression technique, can work with FM tuner without extra Ferrite-bead ponents.
