TPA2005D1DRBRG4 Mono full-differential filter-free Class D amplifier

illustrate   The TPA2005D1 is a 1.4 W high-efficiency filterless Class-D primary ™ audio power amplifier in MSI's BGA, QFN or MSOP package that requires only three external components. Features such as 84% efficiency, a total of 2 mm PCB area of 71,217 dB PSRR at Hz RF rectification immunity, making the phone 15 TPA2005D1 ideal. A fast start-up time of 9 milliseconds with minimal prevalence makes it ideal for TPA2005D1 PDA applications. TPA2005D1 can be driven separately on cellular, handset, speakerphone, and melodic ringtone. The device allows for independent gain of 48μV RMS signal control functions while summarizing each noise reduction. The TPA2005D1 has short circuit and thermal protection.   characteristic   At 1.4 W8 from a 5 V supply Total harmonic distortion = 10% (typical) Longest battery life with less heat Efficiency 8 - Speaker: 84% is in 400 milliwatts 79% is in 100 milliwatts quiescent current of 2.8 mA 0.5μA shutdown current Capable of driving 8-speaker (2.5 V DD≤5.5≤V) and one 4-speaker (2.5 V ≤4.2≤V DD V). There are only three external elements Optimized PWM output stage without the need for an LC output filter The 250 kHz switch generated internally eliminates capacitance and frequency resistance Improved PSRR (-71 dB at 217 Hz) and wide supply voltage (2.5 V to 5.5 V) devices eliminate the need for voltage regulators The fully differential design reduces RF rectification and eliminates bypass capacitors Improved CMRR eliminates two inputs from the coupled capacitor Space-saving package 3 mm × 3 mm QFN package (DRB) 2,5 mm × 2.5 mm MicroStar™ Junior BGA package (ZQY) 3 mm x 5 mm MSOP PowerPAD™ Package (DGN) TPA2010D1 available in 1,45 mm × 1,45 mm WCSP package (YZF). Logic shutdown pin compatibility with 1.8 V is TPA2006D1
