(1) Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.




Description

The TPA6205A1 is a 1.25-W mono fully differential amplifier designed to drive a speaker with at least 8- 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. 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 ms with minimal pop makes the TPA6205A1 ideal for PDA applications.
