TPA6205A1DRBT

illustrate

The TPA6205A1 is a 1.25-W mono fully differential amplifier designed to drive Ω impedance speakers with at least 8 while consuming less than 37 mm^2（ZQVPackage options) has the largest number of applications in the total printed circuit board (PCB). The device operates from 2.5 V to 5.5 V and draws only 1.7 quiescent supply current. The TPA6205A1 is available in a space-saving 2mm × 2mm MicroStar™BGA package, a space-saving 3mm x 3mm QFN (DRB) package.

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