TPA6211A1 - 单声道、全差动 AB 类音频放大器 - 扬声器放大器（AB类/D类） - 低功耗放大器 - TI公司（Texas Instruments，德州仪器）
- Designed for Wireless or Cellular Handsets and PDAs
- 3.1 W Into 3 Ω From a 5-V Supply at THD = 10% (Typ)
- Low Supply Current: 4 mA Typ at 5 V
- Shutdown Current: 0.01 μA Typ
- Fast Startup With Minimal Pop
- Only Three External Components
- Improved PSRR (–80 dB) and Wide Supply Voltage (2.5 V to 5.5 V) for Direct Battery Operation
- Fully Differential Design Reduces RF Rectification
- –63 dB CMRR Eliminates Two Input Coupling Capacitors
- Ideal for Wireless Handsets, PDAs, and Notebook Computers
The TPA6211A1 is a 3.1-W mono fully-differential amplifier designed to drive a speaker with at least 3-Ω impedance while consuming only 20 mm2 total printed-circuit board (PCB) area in most applications. The device operates from 2.5 V to 5.5 V, drawing only 4 mA of quiescent supply current. The TPA6211A1 is available in the space-saving 3-mm × 3-mm SON (DRB) and the 8-pin MSOP-PowerPAD™ (DGN) packages.
Features like –80 dB supply voltage rejection from 20 Hz to 2 kHz, improved RF rectification immunity, small PCB area, and a fast startup with minimal pop makes the TPA6211A1 ideal for PDA and smart phone applications.
