TPA2006D1 2.5W mono filter-free Class D audio power amplifier

illustrate   The TPA2006D1 is a 1.45-W high-efficiency filterless Class D 3 mm × 3 mm QFN package that requires only three external components for audio power amplifiers. The shutdown pin is fully compatible with GPIO 1.8-V logic, such as using a low-power chipset cell. Such as 88% efficiency, -75-dB power supply rejection ratio, improved RF rectification immunity, making small PCB footprint ideal for mobile phone TPA2006D1. The fast start-up time of 1 millisecond to minimize the prevalence makes it ideal for TPA2006D1 PDA applications. TPA2006D1 can be driven separately on cellular, handset, speakerphone, and melodic ringtone. TPA2006D1 allows independent gain while summarizing signals from different sources and has a low-noise layer of 36 μV, A-weighted.   characteristic   Longest battery life with less heat Efficiency 8 - Speaker: 88% is in 400 milliwatts 80% at 100 milliwatts quiescent current of 2.8 mA 0.5μA shutdown current The shutdown pin has a 1.8 V compatible threshold Ability to drive 8-speaker (2.5-volt V DD≤5.5≤V) and one 4-speaker (2.5-volt V DD≤4.2≤five) There are only three external elements Optimized PWM output stage without the need for an LC output filter The internally generated 250-kHz switching frequency eliminates capacitance and resistance Improved PSRR (-75 dB) and wide supply voltage (2.5 V to 5.5 V) eliminate the need for voltage regulators The full differential design reduces RF rectification and eliminates bypass capacitance The improved CMRR eliminates the need for two input-coupled capacitors Space-saving 3 mm × 3 mm QFN package (DRB) apply Ideal for wireless mobile phones and handheld computers or
