TPA6205A1 datasheet



The TPA6205A1 is a 1.25-W mono fully differential amplifier designed to drive a speaker with at least8-Ω impedance while consuming less than 37 mm(2) (ZQV package option) total printed-circuit board (PCB) area in most applications. This device operates from 2.5 V to 5.5 V, drawing only 1.7 mA of quiescent supply current. The TPA6205A1 is available in the space-saving 2 mm x 2 mm MicroStar Junior™ BGA package, and the space saving 3 mm x 3 mm QFN (DRB) package. Features like 85-dB PSRR from 90 Hz to 5 kHz, improved RF-rectification immunity, and small PCB area makes the TPA6205A1 ideal for wireless handsets. A fast start-up time of 4 µs with minimal pop makes the TPA6205A1 ideal for PDA applications.


• 1.25 W Into 8Ω From a 5-V Supply at THD = 1% (Typical)
• Shutdown Pin has 1.8V Compatible Thresholds
• Low Supply Current: 1.7mA Typical
• Shutdown Current < 10µA
• Only Five External Components
– Improved PSRR (90 dB) and Wide Supply Voltage (2.5V to 5.5V) for Direct Battery Operation
– Fully Differential Design Reduces RF Rectification
– Improved CMRR Eliminates Two Input Coupling Capacitors
– C(BYPASS) Is Optional Due to Fully Differential Design and High PSRR
• Available in 3 mm x 3 mm QFN Package (DRB)
• Available in an 8-Pin PowerPAD MSOP (DGN)
• Avaliable in a 2 mm x 2 mm MicroStar Junior BGA Package (ZQV)
