TPA6205A1DRBT

illustrate

The TPA6205A1 is a 1.25-W mono full differential amplifierdesigned to drive Ω impedance speakers with at least 8 and the most applications in total printed circuit board (PCB) consuming less than 37 mm2 (ZQV package option). The device operates from 2.5 V to 5.5 V and draws only 1.7 quiescent supply current. The TPA6205A1 is available in space-saving 2 mm × 2 mm MicroStar™BGA packages and space-saving 3 mm x 3 mm QFN (DRB) packages.

Features such as 85-dB power rejection ratio, from 90 Hz to 5 kHz, improve RF rectification immunity, making it ideal for wireless mobile phone TPA6205A1 with a small PCB area. The minimal popularity of fast start-up time of 4 μs makes it ideal for TPA6205A1 PDA applications.
