Description
The TPA2006D1 is a 1.45-W high efficiency filter-free class-D audio power amplifier in a 3 mm × 3 mm QFN package that requires only three external components.
- Maximum Battery Life and Minimum Heat
- Efficiency With an 8- Speaker:
- 88% at 400 mW
- 80% at 100 mW
- 2.8-mA Quiescent Current
- 0.5-µA Shutdown Current
- Shutdown Pin has 1.8-V Compatible Thresholds
- Capable of Driving an 8- Speaker (2.5 V = VDD = 5.5 V) and a 4- Speaker (2.5 V = VDD = 4.2 V)
- Only Three External Components
- Optimized PWM Output Stage Eliminates LC Output Filter
- Internally Generated 250-kHz Switching Frequency Eliminates Capacitor and Resistor
- Improved PSRR (–75 dB) and Wide Supply Voltage (2.5 V to 5.5 V) Eliminates Need for a Voltage Regulator
- Fully Differential Design Reduces RF Rectification and Eliminates Bypass Capacitor
- Improved CMRR Eliminates Two Input Coupling Capacitors
