•
Low Supply Current: 1.7mA Typical  
Shutdown Current < 10µA  
DESCRIPTION  
The TPA6205A1 is a 1.25-W mono fully differential  
amplifier designed to drive a speaker with at least  
8-Ω impedance while consuming less than 37 mm2  
(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.  
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  
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.
